Pull NFS client updates from Anna Schumaker:
 "New Features:

   - Initial support for fs_locations and server trunking

  Bugfixes and Cleanups:

   - Cleanups to how the "struct cred *" is handled for the
     nfs_access_entry

   - Ensure the server has an up to date ctimes before hardlinking or
     renaming

   - Update 'blocks used' after writeback, fallocate, and clone

   - nfs_atomic_open() fixes

   - Improvements to sunrpc tracing

   - Various null check & indenting related cleanups

   - Some improvements to the sunrpc sysfs code:
      - Use default_groups in kobj_type
      - Fix some potential races and reference leaks

   - A few tracepoint cleanups in xprtrdma"

[ This should have gone in during the merge window, but didn't. The
  original pull request - sent during the merge window - had gotten
  marked as spam and discarded due missing DKIM headers in the email
