xfs: skip fragmentation tests when alwayscow mode is enabled, part 2
If the always_cow debugging flag is enabled, all file writes turn into
copy writes. This dramatically ramps up fragmentation in the filesystem
(intentionally!) so there's no point in complaining about fragmentation.
I missed these two in the original commit because readahead for md5sum
would create large folios at the start of the file. This resulted in
the fdatatasync after the random writes issuing writeback for the whole
large folio, which reduced file fragmentation to the point where this
test started passing.
With Ritesh's patchset implementing sub-folio dirty tracking, this test
goes back to failing due to high fragmentation (as it did before large
folios) so we need to mask these off too.
