Btrfs: don't keep trying to build clusters if we are fragmented If we are extremely fragmented then we won't be able to create a free_cluster. So if this happens set last_ptr->fragmented so that all future allcations will give up trying to create a cluster. When we unpin extents we will unset ->fragmented if we free up a sufficient amount of space in a block group. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Chris Mason <clm@fb.com>
