I think this is specific to XFS. Can you show me the F2FS code that
restricts the length of an atomic write to a power of two? I haven't
found it. The only power-of-two check that I found in F2FS is the
following (maybe I overlooked something):

$ git grep -nH is_power fs/f2fs
fs/f2fs/super.c:3914: if (!is_power_of_2(zone_sectors)) {

Thanks,

Bart.
