From 29bce2f3997a8dc5195b7a7724362d1e55df7bb2 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 7 Feb 2014 12:21:23 -0500 Subject: Btrfs: unlock extent and pages on error in cow_file_range When I converted the BUG_ON() for the free_space_cache_inode in cow_file_range I made it so we just return an error instead of unlocking all of our various stuff. This is a mistake and causes us to hang when we run into this. This patch fixes this problem.
