Merge tag 'afs-20170316' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull AFS fixes from David Howells:
 "Fixes to the AFS filesystem in the kernel.

  They fix a variety of bugs. These include some issues fixed for
  consistency with other AFS implementations:

   - handle AFS mode bits better

   - use the client mtime rather than the server mtime in the protocol

   - handle the server returning more or less data than was requested in
     a FetchData call

   - distinguish mountpoints from symlinks based on the mode bits rather
     than preemptively reading every symlink to find out what it
     actually represents

  One other notable change for the user is that files are now flushed on
  close analogously with other network filesystems"
