Josef Bacik 07103a3cdb Btrfs: fix free space accounting when unpinning extents ... This patch fixes what I hope is the last early ENOSPC bug left. I did not know that pinned extents would merge into one big extent when inserted on to the pinned extent tree, so I was adding free space to a block group that could possibly span multiple block groups. This is a big issue because first that space doesn't exist in that block group, and second we won't actually use that space because there are a bunch of other checks to make sure we're allocating within the constraints of the block group. This patch fixes the problem by adding the btrfs_add_free_space to btrfs_update_pinned_extents which makes sure we are adding the appropriate amount of free space to the appropriate block group. Thanks much to Lee Trager for running my myriad of debug patches to help me track this problem down. Thank you, Signed-off-by: Josef Bacik <jbacik@redhat.com>		16 years ago
