From 41415730a1050499fbd63b3f7dd59b3a4c3bb91a Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 16 Mar 2011 13:59:32 -0400 Subject: [PATCH] Btrfs: check return value of btrfs_search_slot properly Doing an audit of where we use btrfs_search_slot only showed one place where we don't check the return value of btrfs_search_slot properly. Just fix mark_extent_written to see if btrfs_search_slot failed and act accordingly.
