Wong" , Brian Foster 4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Darrick J. Wong" commit 77aff8c76425c8f49b50d0b9009915066739e7d2 upstream. If we fail a mount on account of cow recovery errors, it's possible that a previous quotacheck left some dquots in memory. The bailout clause of xfs_mountfs forgets to purge these, and so we leak them. Fix that. Signed-off-by: Darrick J.
