It doesn't allocate extent_state and check the result properly: - in set_extent_bit, it doesn't allocate extent_state if the path is not allowed wait - in clear_extent_bit, it doesn't check the result after atomic-ly allocate, we trigger BUG_ON() if it's fail - if allocate fail, we trigger BUG_ON instead of returning -ENOMEM since the return value of clear_extent_bit() is ignored by many callers Signed-off-by: NXiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: NChris Mason <chris.mason@oracle.com>
