Subject: Questions about file extents and alignment
Date: Fri, 13 Apr 2012 10:42:50 +0200 [thread overview]
Message-ID: <CAB9VWqA2bF26CnaeYCT4zfeLjDkNeG+DCQBnQb-uDTPnBh_8qA@mail.gmail.com> (raw)
Hello,
Using find-new, I've seen that all regular extents seem to be 4k
aligned. Inline extents were not aligned.
Is it guaranteed that all regular extents are 4k aligned in
disk_bytenr, disk_num_bytes, offset and num_bytes? Even if COW or what
ever may happen happens?
Thanks,
Alex.
