From 8fccfc829a66b8b879c6672940523a402a786ce1 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Wed, 9 May 2007 17:34:26 -0700 Subject: [PATCH] ocfs2: fix inode leak We weren't cleaning up our inode reference on error in ocfs2_reserve_local_alloc_bits(). Add a check for error return and iput() if need be. Move the code to set the alloc context inode info to the end of the function so we don't have any possibility of passing back a bad pointer.
