VFS: Fix the remaining automounter semantics regressions
The concensus seems to be that system calls such as stat() etc should not trigger an automount. Neither should the l* versions. This patch therefore adds a LOOKUP_AUTOMOUNT flag to tag those lookups that _should_ trigger an automount on the last path element. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> [ Edited to leave out the cases that are already covered by LOOKUP_OPEN, LOOKUP_DIRECTORY and LOOKUP_CREATE - all of which also fundamentally force automounting for their own reasons - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
