From 6c36547293e6c46fe5df46e5e1b9ce9babb9eb37 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 25 Oct 2011 13:59:47 +0200 Subject: VFS: Fix the remaining automounter semantics regressions commit 815d405ceff0d6964683f033e18b9b23a88fba87 upstream. 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.
