Btrfs: do not needlessly restart the transaction for enospc
We will stop and restart a transaction every time we move to a different leaf when truncating a file. This is for enospc reasons, but really we could probably get away with doing this a little better by actually working until we hit an ENOSPC. So add a ->failfast flag to the block_rsv and set it when we do truncates which will fail as soon as the block rsv runs out of space, and then at that point we can stop and restart the transaction and refill the block rsv and carry on. This will make rm'ing of a file with lots of extents a bit faster. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
