Subject[ 72/73] kernel/audit_tree.c: tree will leak memory when failure occurs in audit_trim_trees()
Date
3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chen Gang <gang.chen@asianux.com>

commit 12b2f117f3bf738c1a00a6f64393f1953a740bd4 upstream.

audit_trim_trees() calls get_tree(). If a failure occurs we must call
put_tree().

[akpm@linux-foundation.org: run put_tree() before mutex_lock() for small scalability improvement]
