From d8c8133eb0460a183e69cf8a5d722688916960de Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 16 Feb 2015 03:21:17 +0000 Subject: [PATCH] vfs: Fix vfsmount_lock imbalance in path_init() When backporting commit 4023bfc9f351 ("be careful with nd->inode in path_init() and follow_dotdot_rcu()"), I failed to account for the vfsmount_lock that is used in 3.2 but not upstream. path_init() takes the lock if performing RCU lookup, but must drop it if (and only if) it subsequently fails.
