NFSv4.2: Update mode bits after ALLOCATE and DEALLOCATE
The fallocate call invalidates suid and sgid bits as part of normal operation. We need to mark the mode bits as invalid when using fallocate with an suid so these will be updated the next time the user looks at them. This fixes xfstests generic/683 and generic/684. Reported-by: Yue Cui <cuiyue-fnst@fujitsu.com> Fixes: 913eca1aea87 ("NFS: Fallocate should use the nfs4_fattr_bitmap") Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
