nfs: Fix ugly referral attributes
Before traversing a referral and performing a mount, the mounted-on directory looks strange: dr-xr-xr-x. 2 4294967294 4294967294 0 Dec 31 1969 dir.0 nfs4_get_referral is wiping out any cached attributes with what was returned via GETATTR(fs_locations), but the bit mask for that operation does not request any file attributes. Retrieve owner and timestamp information so that the memcpy in nfs4_get_referral fills in more attributes. Changes since v1: - Don't request attributes that the client unconditionally replaces - Request only MOUNTED_ON_FILEID or FILEID attribute, not both - encode_fs_locations() doesn't use the third bitmask word Fixes: 6b97fd3d ("NFSv4: Follow a referral") Suggested-by: NPradeep Thomas <pradeepthomas@gmail.com> Signed-off-by: NChuck Lever <chuck.lever@oracle.com> Cc: stable@vger.kernel.org Signed-off-by: NAnna Schumaker <Anna.Schumaker@Netapp.com>
