Hi. There was an unnecessary line in function, allocate_data_block.
In this function, we already choosed old curseg(Y) and then we always allocate
new address(∈Y) from it.
After that we call refresh_sit_entry(sbi, old_blkaddr, *new_blkaddr).
In that function, we call located_dirty_segment with old seg(X) and old
curseg(Y).
So, because we've done about old curseg(Y),
calling locate_dirty_segment(sbi, old_cursegno) again is redundant.
Thanks. :-)
