ext4: simple cleanup in fiemap codepath
This commit is simple cleanup of fiemap codepath which has not been included in previous commit to make the changes clearer. In this commit we rename cbex variable to newex in ext4_fill_fiemap_extents() because callback is no longer present Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
