[Luis Henriques]

3.5.7.22 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anand Avati <avati at redhat.com>

commit d331a415aef98717393dda0be69b7947da08eba3 upstream.

Calls like setxattr and removexattr result in updation of ctime.
Therefore invalidate inode attributes to force a refresh.
