Li Zefan 120d66eec0 btrfs: Add a helper try_merge_free_space() ... When adding a new extent, we'll firstly see if we can merge this extent to the left or/and right extent. Extract this as a helper try_merge_free_space(). As a side effect, we fix a small bug that if the new extent has non-bitmap left entry but is unmergeble, we'll directly link the extent without trying to drop it into bitmap. This also prepares for the next patch. Reviewed-by: Josef Bacik <josef@redhat.com> Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>		2011-01-27 01:04:50 +08:00
