      wrappers for ->i_mutex access · 5955102c
      Al Viro authored
      parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested},
      inode_foo(inode) being mutex_foo(&inode->i_mutex).
      Please, use those for access to ->i_mutex; over the coming cycle
      ->i_mutex will become rwsem, with ->lookup() done with it held
      only shared.

         - promotion of XFS_IOC_FS[GS]ETXATTR ioctl to the vfs level so that
           it can be shared with other filesystems.  The ext4 project quota
           functionality is the first target for this.  The commits in this
           series have not been updated with review or final SOB tags because

      ocfs2: NFS hangs in __ocfs2_cluster_lock due to race with ocfs2_unblock_lock · b1b1e15e
      Tariq Saeed authored
      NFS on a 2 node ocfs2 cluster each node exporting dir.  The lock causing
      the hang is the global bit map inode lock.  Node 1 is master, has the
      lock granted in PR mode; Node 2 is in the converting list (PR -> EX).
      There are no holders of the lock on the master node so it should
      downconvert to NL and grant EX to node 2 but that does not happen.
      BLOCKED + QUEUED in lock res are set and it is on osb blocked list.
      Threads are waiting in __ocfs2_cluster_lock on BLOCKED.  One thread
      wants EX, rest want PR.  So it is as though the downconvert thread needs
      to be kicked to complete the conv.
      The hang is caused by an EX req coming into __ocfs2_cluster_lock on the
      heels of a PR req after it sets BUSY (drops l_lock, releasing EX
      thread), forcing the incoming EX to wait on BUSY without doing anything.
      PR has called ocfs2_dlm_lock, which sets the node 1 lock from NL -> PR,
      queues ast.
      At this time, upconvert (PR ->EX) arrives from node 2, finds conflict
      with node 1 lock in PR, so the lock res is put on dlm thread's dirty
      After ret from ocf2_dlm_lock, PR thread now waits behind EX on BUSY till
      awoken by ast.
      Now it is dlm_thread that serially runs dlm_shuffle_lists, ast, bast, in
      that order.  dlm_shuffle_lists ques a bast on behalf of node 2 (which
      will be run by dlm_thread right after the ast).  ast does its part, sets
      UPCONVERT_FINISHING, clears BUSY and wakes its waiters.  Next,
      dlm_thread runs bast.  It sets BLOCKED and kicks dc thread.  dc thread
      runs ocfs2_unblock_lock, but since UPCONVERT_FINISHING set, skips doing
      anything and reques.
      Inside of __ocfs2_cluster_lock, since EX has been waiting on BUSY ahead
      of PR, it wakes up first, finds BLOCKED set and skips doing anything but
      clearing UPCONVERT_FINISHING (which was actually "meant" for the PR
      thread), and this time waits on BLOCKED.  Next, the PR thread comes out
      of wait but since UPCONVERT_FINISHING is not set, it skips updating the
      l_ro_holders and goes straight to wait on BLOCKED.  So there, we have a
      hang! Threads in __ocfs2_cluster_lock wait on BLOCKED, lock res in osb
      blocked list.  Only when dc thread is awoken, it will run
      ocfs2_unblock_lock and things will unhang.
      One way to fix this is to wake the dc thread on the flag after clearing

      reiserfs_iget() returns either NULL or error code in ERR_PTR.  And we

      ratelimit: fix bug in time interval by resetting right begin time · c2594bc3
      Jaewon Kim authored
      rs->begin in ratelimit is set in two cases.
       1) when rs->begin was not initialized
       2) when rs->interval was passed
      For case #2, current ratelimit sets the begin to 0.  This incurrs
      improper suppression.  The begin value will be set in the next ratelimit
      call by 1).  Then the time interval check will be always false, and
      rs->printed will not be initialized.  Although enough time passed,
      ratelimit may return 0 if rs->printed is not less than rs->burst.  To
      reset interval properly, begin should be jiffies rather than 0.
      For an example code below:
          static DEFINE_RATELIMIT_STATE(mylimit, 1, 1);
          for (i = 1; i <= 10; i++) {
              if (__ratelimit(&mylimit))
                  printk("ratelimit test count %d\n", i);
      test result in the current code shows suppression even there is 3 seconds sleep.

              return 0;
      It happens on munlock_vma_page() due to unfortunate choice of nr_pages
      data type:
          __mod_zone_page_state(zone, NR_MLOCK, -nr_pages);
      For unsigned int nr_pages, implicitly casted to long in
      __mod_zone_page_state(), it becomes something around UINT_MAX.
      munlock_vma_page() usually called for THP as small pages go though
      Let's make nr_pages signed int.
      Similar fixes in 6cdb18ad ("mm/vmstat: fix overflow in
      mod_zone_page_state()") used `long' type, but `int' here is OK for a
      count of the number of sub-pages in a huge page.

      Merge branch 'uaccess' (batched user access infrastructure) · 404a4741
      Linus Torvalds authored
      Expose an interface to allow users to mark several accesses together as
      being user space accesses, allowing batching of the surrounding user
      space access markers (SMAP on x86, PAN on arm64, domain register
      switching on arm).
      This is currently only used for the user string lenth and copying
      functions, where the SMAP overhead on x86 drowned the actual user
      accesses (only noticeable on newer microarchitectures that support SMAP
      in the first place, of course).
      * user access batching branch:
        Use the new batched user accesses in generic user string handling
        Add 'unsafe' user access functions for batched accesses

      pwm: Mark all devices as "might sleep" · ff01c944
      Thierry Reding authored
      Commit d1cd2142 ("pwm: Set enable state properly on failed call to
      enable") introduced a mutex that is needed to protect internal state of
      PWM devices. Since that mutex is acquired in pwm_set_polarity() and in
      pwm_enable() and might potentially block, all PWM devices effectively
      become "might sleep".
      It's rather pointless to keep the .can_sleep field around, but given
      that there are external users let's postpone the removal for the next
      release cycle.

      Pull more power management and ACPI updates from Rafael Wysocki:
       "This includes fixes on top of the previous batch of PM+ACPI updates
        and some new material as well.
        From the new material perspective the most significant are the driver
        core changes that should allow USB devices to stay suspended over
        system suspend/resume cycles if they have been runtime-suspended
        already beforehand.  Apart from that, ACPICA is updated to upstream
        revision 20160108 (cosmetic mostly, but including one fixup on top of
        the previous ACPICA update) and there are some devfreq updates the
        didn't make it before (due to timing).
        A few recent regressions are fixed, most importantly in the cpuidle
        menu governor and in the ACPI backlight driver and some x86 platform
        drivers depending on it.
        Some more bugs are fixed and cleanups are made on top of that.
         - Modify the driver core and the USB subsystem to allow USB devices
           to stay suspended over system suspend/resume cycles if they have
           been runtime-suspended already beforehand and fix some bugs on top
           of these changes (Tomeu Vizoso, Rafael Wysocki).
         - Update ACPICA to upstream revision 20160108, including updates of
           the ACPICA's copyright notices, a code fixup resulting from a
           regression fix that was necessary in the upstream code only (the
           regression fixed by it has never been present in Linux) and a
           compiler warning fix (Bob Moore, Lv Zheng).
         - Fix a recent regression in the cpuidle menu governor that broke it
           on practically all architectures other than x86 and make a couple
           of optimizations on top of that fix (Rafael Wysocki).
         - Clean up the selection of cpuidle governors depending on whether or
           not the kernel is configured for tickless systems (Jean Delvare).
         - Revert a recent commit that introduced a regression in the ACPI
           backlight driver, address the problem it attempted to fix in a
           different way and revert one more cosmetic change depending on the
           problematic commit (Hans de Goede).
         - Add two more ACPI backlight quirks (Hans de Goede).
         - Fix a few minor problems in the core devfreq code, clean it up a
           bit and update the MAINTAINERS information related to it (Chanwoo
           Choi, MyungJoo Ham).
         - Improve an error message in the ACPI fan driver (Andy Lutomirski).

      Pull ARM SoC multiplatform code updates from Arnd Bergmann:
       "This branch is the culmination of 5 years of effort to bring the ARMv6
        and ARMv7 platforms together such that they can all be enabled and
        boot the same kernel.  It has been a tremendous amount of cleanup and
        refactoring by a huge number of people, and creation of several new
        (and major) subsystems to better abstract out all the platform details
        in an appropriate manner.
        The bulk of this branch is a large patchset from Arnd that brings
        several of the more minor and older platforms we have closer to
        multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
        and realview Much of this is moving around header files from old mach
        directories, but there are also some cleanup patches of debug_ll
        (lowlevel debug per-platform options) and other parts.
        Linus Walleij also has some patchs to clean up the older ARM Realview
        platforms by finally introducing DT support, and Rob Herring has some
        for ARM Versatile which is now DT-only.  Both of these platforms are
        now multiplatform.

      Pull SCSI target updates from Nicholas Bellinger:
       "The highlights this round include:
         - Introduce configfs support for unlocked configfs_depend_item()
           (krzysztof + andrezej)
         - Conversion of usb-gadget target driver to new function registration
           interface (andrzej + sebastian)
         - Enable qla2xxx FC target mode support for Extended Logins (himansu +
         - Enable qla2xxx FC target mode support for Exchange Offload (himansu +
         - Add qla2xxx FC target mode irq affinity notification + selective
           command queuing.  (quinn + himanshu)
         - Fix iscsi-target deadlock in se_node_acl configfs deletion (sagi +
         - Convert se_node_acl configfs deletion + se_node_acl->queue_depth to
           proper se_session->sess_kref + target_get_session() usage.  (hch +
           sagi + nab)
         - Fix long-standing race between se_node_acl->acl_kref get and
           get_initiator_node_acl() lookup.  (hch + nab)
         - Fix target/user block-size handling, and make sure netlink reaches
           all network namespaces (sheng + andy)
        Note there is an outstanding bug-fix series for remote I_T nexus port
        TMR LUN_RESET has been posted and still being tested, and will likely
        become post -rc1 material at this point"

      Do not enable CONFIG_IO_STRICT_DEVMEM by default · 19a3dd76
      Dan Williams authored
      Larry Finger reports:
       "My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for
        the 4.4-git series".
      This is likely due to X still needing /dev/mem access on this platform.
      CONFIG_IO_STRICT_DEVMEM is not yet safe to turn on when
      Remove the default so that old configurations do not change behavior.
      Fixes: 90a545e9 ("restrict /dev/mem to idle io memory ranges")
