From 851a8a7fd451db3dcd5d44d784083f0f66b24d57 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Wed, 18 Jul 2007 00:49:08 -0700 Subject: [PATCH] dm: fix memory leak in dm_create_persistent() when starting metadata update thread fails If, in dm_create_persistent(), the call to create_singlethread_workqueue() fails then we'll return without freeing the memory allocated to 'ps', thus leaking sizeof(struct pstore) bytes. This patch fixes the leak.
