      task IO accounting: move all IO statistics in struct task_io_accounting · 940389b8
      Andrea Righi authored
      Simplify the code of include/linux/task_io_accounting.h.
      It is also more reasonable to have all the task i/o-related statistics in a
      single struct (task_io_accounting).

      NFS: Ensure we call nfs_sb_deactive() after releasing the directory inode · 744d18db
      Trond Myklebust authored
      In order to avoid the "Busy inodes after unmount" error message, we need to
      ensure that nfs_async_unlink_release() releases the super block after the
      call to nfs_free_unlinkdata().

      The new super.c:nfs_remount function doesn't check the validity of the
      options/options4 pointers. Unfortunately, this seems to happend.
      The obvious patch seems to check the pointers, and not to do anything if
      the happend to be NULL.
      Tested on an XScale PXA255 system, latest git.

      commit 3e970473
       ("x86: boot secondary
      cpus through initial_code") causes the kernel to crash when a CPU is
      brought online after the read only sections have been write
      protected. The write to initial_code in do_boot_cpu() fails.
      Move inital_code to .cpuinit.data section.

      missing bits of net-namespace / sysctl · eeb61f71
      Al Viro authored
      Piss-poor sysctl registration API strikes again, film at 11...
      What we really need is _pathname_ required to be present in already
      registered table, so that kernel could warn about bad order.  That's the
      next target for sysctl stuff (and generally saner and more explicit
      order of initialization of ipv[46] internals wouldn't hurt either).
      For the time being, here are full fixups required by ..._rotable()
      stuff; we make per-net sysctl sets descendents of "ro" one and make sure
      that sufficient skeleton is there before we start registering per-net

      [SCSI] extend the last_sector_bug flag to cover more sectors · 2b142900
      Alan Jenkins authored
      The last_sector_bug flag was added to work around a bug in certain usb
      cardreaders, where they would crash if a multiple sector read included the
      last sector. The original implementation avoids this by e.g. splitting an 8
      sector read which includes the last sector into a 7 sector read, and a single
      sector read for the last sector.  The flag is enabled for all USB devices.
      This revealed a second bug in other usb cardreaders, which crash when they
      get a multiple sector read which stops 1 sector short of the last sector.
      Affected hardware includes the Kingston "MobileLite" external USB cardreader
      and the internal USB cardreader on the Asus EeePC.
      Extend the last_sector_bug workaround to ensure that any access which touches
      the last 8 hardware sectors of the device is a single sector long.  Requests
      are shrunk as necessary to meet this constraint.
      This gives us a safety margin against potential unknown or future bugs
      affecting multi-sector access to the end of the device.  The two known bugs
      only affect the last 2 sectors.  However, they suggest that these devices
      are prone to fencepost errors and that multi-sector access to the end of the
      device is not well tested.  Popular OS's use multi-sector accesses, but they
      rarely read the last few sectors.  Linux (with udev & vol_id) automatically
      reads sectors from the end of the device on insertion.  It is assumed that
      single sector accesses are more thoroughly tested during development.

      avr32: some mmc/sd cleanups · 3c26e170
      David Brownell authored
      Minor cleanups for the MMC/SD support on avr32:
       - Make at32_add_device_mci() properly initialize "missing"
         platform data ... so boards like STK1002 won't try GPIO 0.
       - Switch over to gpio_is_valid() instead of testing for only
         one designated value.
       - Provide STK1002 platform data for the unlikely case that
         switches are set so first Ethernet controller isn't in use.
         (That's the only way to get card detect and writeprotect
         switch sensing on the STK1000.)
      And get rid of one "unused variable" warning.

      [ARM] Fix shared mmap when more than two maps of the same file exist · 53cdb27a
      Russell King authored
      The shared mmap code works fine for the test case, which only checked
      for two shared maps of the same file.  However, three shared maps
      result in one mapping remaining cached, resulting in stale data being
      visible via that mapping.  Fix this.

      [ARM] fix VIPT/VIVT macro optimisations, add comments · daf93dd5
      Russell King authored
      cacheflush.h was doing:
      ... VIVT only stuff
      ... VIPT only stuff
      ... VIVT or VIPT stuff
      which is clearly bogus - we would only ever use the "VIVT or VIPT" case
      when both VIVT and VIPT are not selected.  Fix this.
      Add comments to each case, including noting the impossibility of
      correctly detecting the cache type of ARM926 and ARMv6 cores from
      the cache type register in the "VIVT or VIPT" case.
