[PATCH 0/2] nfs_complete_rename() calls d_move() without i_mutex

[Benjamin Coddington <bcodding@redhat.com>]

Once commit 920b4530fb80430ff30ef83efe21ba1fa5623731 "NFS: nfs_rename()
handle -ERESTARTSYS dentry left behind" moved the local d_move() into the
RPC asyncronous context, d_move() could be called without holding the
directories' i_mutex.

Let's revert that commit, and a follow-up fix for it in 1/2, and then fix
the original problem once more by forcing a revalidation of the old and new
directories if we notice that the rename was interrupted in 2/2.

Benjamin Coddington (2):
  Revert "NFS: nfs_rename() handle -ERESTARTSYS dentry left behind"
  NFS: nfs_rename() - revalidate directories on -ERESTARTSYS
