Hi all,
We realized late that we could optimize the punch hole code by skipping
ext4_ext_remove_space, and directly calling ext4_ext_rm_leaf. Since
punch hole is done through map blocks, the path to the extent is already
known, so we do not need to look it up again. The extra parameter that
was added in ext4_ext_remove_space is removed since we no longer need it.
