ext4: Remove unneeded BUG_ON() in ext4_move_extents()
The ext4_move_extents() functions checks with BUG_ON() whether the exchanged blocks count accords with request blocks count. But, if the target range (orig_start + len) includes sparse block(s), 'moved_len' (exchanged blocks count) does not agree with 'len' (request blocks count), since sparse block is not counted in 'moved_len'. This causes us to hit the BUG_ON(), even though the function succeeded. Signed-off-by: Akira Fujita <a-fujita@rs.jp.nec.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
