Btrfs: don't lock bits in the extent tree during writepage At writepage time, we have the page locked and we have the extent_map entry for this extent pinned in the extent_map tree. So, the page can't go away and its mapping can't change. There is no need for the extra extent_state lock bits during writepage. Signed-off-by: Chris Mason <chris.mason@oracle.com>
