Subject: kernel/audit_tree.c: tree will leak memory when failure occurs in audit_trim_trees()
From: Chen Gang <gang.chen@xxxxxxxxxxx>
commit 12b2f117f3bf738c1a00a6f64393f1953a740bd4 upstream.
audit_trim_trees() calls get_tree(). If a failure occurs we must call
put_tree().
[akpm@xxxxxxxxxxxxxxxxxxxx: run put_tree() before mutex_lock() for small scalability improvement]
