SVN rev 190970 on 2009-04-12 17:43:41Z by kan
Reimplement r189287 for -stable:
Change vfs_busy to wait until an outcome of pending unmount
operation is known and to retry or fail accordingly to that
outcome. This fixes the problem with namespace traversing
programs failing with random ENOENT errors if someone just
happened to try to unmount that same filesystem at the same
time.
