From fd79b77117f16264206ed2618199d42e93cc8f09 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 28 Nov 2007 16:21:31 -0800 Subject: [PATCH] ipc: lost unlock and fput in mqueue.c on error path 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.
