Unfortunately backporting the fix in any sensible time
period is beyond me. At least one of the files being
patched doesn't even exist in the 1.3.1 release. If I
try to remedy this by applying other updates to the
xfs code first I'm going to get into the situation
where other core kernel updates are also required.
These will too have their dependencies. I think it
really needs somebody who knows the xfs code and
understands the problem to produce a 1.3.1 fix.
You said that one of my workarounds would be to
downgrade xfstools (or at least mkfs.xfs). Wouldn't
it be better if the latest released version of
xfstools worked correctly with the latest released
version of xfs? Perhaps its possible for mkfs.xfs to
detect the use of xfs1.3.1 (and earlier?) and not
create large allocation groups under those conditions.
Kind Regards,
Alex
