NFS: Filter cache invalidation when holding a delegation
If the client holds a delegation, then ensure we filter out attempts to invalidate the size, owner, group owner, or mode unless we made the change, in which case, check that NFS_INO_REVAL_FORCED is set by the caller. Always filter out attempts to invalidate the change attribute and size, since we are authoritative for those. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
