       "Mostly updates to the perf tool plus two fixes to the kernel core code:
      
         - Handle tracepoint filters correctly for inherited events (Peter
           Zijlstra)
      
         - Prevent a deadlock in perf_lock_task_context (Paul McKenney)

           --full-paths' (Michael Petlan)

           tarballs, i.e. out of tree building (Arnaldo Carvalho de Melo)
      
         - Add the llvm-src-base.c and llvm-src-kbuild.c files, generated by
           the 'perf test' LLVM entries, when running it in-tree, to
           .gitignore (Yunlong Song)
      
         - libbpf error reporting improvements, using a strerror interface to
           more precisely tell the user about problems with the provided
           scriptlet, be it in C or as a ready made object file (Wang Nan)
      
         - Do not be case sensitive when searching for matching 'perf test'
           entries (Arnaldo Carvalho de Melo)
      
         - Inform the user about objdump failures in 'perf annotate' (Andi
           Kleen)
      
         - Improve the LLVM 'perf test' entry, introduce a new ones for BPF
           and kbuild tests to check the environment used by clang to compile
           .c scriptlets (Wang Nan)"

      Pull final round of SCSI updates from James Bottomley:
       "Sorry for the delay in this patch which was mostly caused by getting
        the merger of the mpt2/mpt3sas driver, which was seen as an essential

        Unfortunately, this caused a compile failure (detected by linux-next),
        which then had to be fixed up and incubated.

      Pull SCSI target updates from Nicholas Bellinger:
       "This series contains HCH's changes to absorb configfs attribute
        ->show() + ->store() function pointer usage from it's original
        tree-wide consumers, into common configfs code.
      
        It includes usb-gadget, target w/ drivers, netconsole and ocfs2
        changes to realize the improved simplicity, that now renders the
        original include/target/configfs_macros.h CPP magic for fabric drivers
        and others, unnecessary and obsolete.
      
        And with common code in place, new configfs attributes can be added
        easier than ever before.
      
        Note, there are further improvements in-flight from other folks for
        v4.5 code in configfs land, plus number of target fixes for post -rc1
        code"
      
      In the meantime, a new user of the now-removed old configfs API came in
      through the char/misc tree in commit 7bd1d409 ("stm class: Introduce
      an abstraction for System Trace Module devices").
      
      This merge resolution comes from Alexander Shishkin, who updated his stm
      class tracing abstraction to account for the removal of the old
      show_attribute and store_attribute methods in commit 51798222
      ("configfs: remove old API") from this pull.  As Alexander says about
      that patch:
      
       "There's no need to keep an extra wrapper structure per item and the
        awkward show_attribute/store_attribute item ops are no longer needed.
      
        This patch converts policy code to the new api, all the while making
        the code quite a bit smaller and easier on the eyes.
      
        Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"
      
      That patch was folded into the merge so that the tree should be fully
      bisectable.

      f2fs: xattr simplifications · 29608d20
      Andreas Gruenbacher authored
      Now that the xattr handler is passed to the xattr handler operations, we
      have access to the attribute name prefix, so simplify
      f2fs_xattr_generic_list.
      
      Also, f2fs_xattr_advise_list is only ever called for
      f2fs_xattr_advise_handler; there is no need to double check for that.

      9p: xattr simplifications · e409de99
      Andreas Gruenbacher authored
      Now that the xattr handler is passed to the xattr handler operations, we
      can use the same get and set operations for the user, trusted, and security
      xattr namespaces.  In those namespaces, we can access the full attribute
      name by "reattaching" the name prefix the vfs has skipped for us.  Add a
      xattr_full_name helper to make this obvious in the code.
      
      For the "system.posix_acl_access" and "system.posix_acl_default"
      attributes, handler->prefix is the full attribute name; the suffix is the
      empty string.

      xattr handlers: Pass handler to operations instead of flags · d9a82a04
      Andreas Gruenbacher authored
      The xattr_handler operations are currently all passed a file system
      specific flags value which the operations can use to disambiguate between
      different handlers; some file systems use that to distinguish the xattr
      namespace, for example.  In some oprations, it would be useful to also have
      access to the handler prefix.  To allow that, pass a pointer to the handler
      to operations instead of the flags value alone.

      jffs2: Add missing capability check for listing trusted xattrs · bf781714
      Andreas Gruenbacher authored
      The vfs checks if a task has the appropriate access for get and set
      operations, but it cannot do that for the list operation; the file system
      must check for that itself.

      ubifs: Remove unused security xattr handler · 13d3408f
      Andreas Gruenbacher authored
      Ubifs installs a security xattr handler in sb->s_xattr but doesn't use the
      generic_{get,set,list,remove}xattr inode operations needed for processing
      this list of attribute handlers; the handler is never called.  Instead,
      ubifs uses its own xattr handlers which also process security xattrs.
      
      Remove the dead code.

      vfs: Fix the posix_acl_xattr_list return value · dae5f57a
      Andreas Gruenbacher authored
      When a filesystem that contains POSIX ACLs is mounted without ACL support
      (-o noacl), the appropriate behavior is not to list any existing POSIX ACL
      xattrs.  The return value for list xattr handlers in this case is 0, not an
      error code: several filesystems that use the POSIX ACL xattr handlers do
      not expect the list operation to fail.
      
      Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for
      symlinks in the first place.
