ext4: Remove unneeded BUG_ON() in ext4_move_extents() From: Akira Fujita <a-fujita@xxxxxxxxxxxxx> ext4_move_extents() 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 accord with 'len' (request blocks count), since sparse block is not counted in 'moved_len'. Therefore we hit BUG_ON(), though it succeeded.
