I will remove this statement in the next revision.
I was partially misled by [1] where it is stated "Segments are collected into sections. There is genuine flexibility in the size of a section, though it must be a power of two.". Just FYI, when I did a quick check, there are some assumptions in the zoned support for f2fs which assumes the zoned device size is a power of 2 such as in the __f2fs_issue_discard_zone. So if I am not wrong, when we remove those assumptions in f2fs for zone size, then everything should work fine provided the zone size is a multiple of 2MB. Am I missing something here? I am new to f2fs but is there testsuite that I can run for f2fs apart from the two tests listed in (x)fstests?
