Subject: [git pull] vfs fix
Date: Thu, 24 Feb 2011 07:20:08 +0000 [thread overview]
Message-ID: <20110224072008.GY22723@ZenIV.linux.org.uk> (raw)
Fix for very unpleasant braino in do_umount(); the effect was
that if umount(name, MNT_EXPIRE) failed with -EBUSY it left the kernel
with doubly-taken vfsmount_lock. The next attempt to mount or umount
something would deadlock, of course... Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Unlock vfsmount_lock in do_umount
