Subject: [PATCH][IPC] Lost unlock and fput in mqueue.c on error path
Date: Wed, 21 Nov 2007 16:54:58 +0300 [thread overview]
Message-ID: <474438B2.9010200@openvz.org> (raw)
The error path in sys_mq_getsetattr() after the call to
audit_mq_getsetattr() is wrong - the info->lock is not
unlocked and the struct file *filp is not put.
Fix them both.
