Ah - this was reported as a 2.6.26 -> 2.6.27 regression, not a
.27->.28-rcX regression.

Even so, it's not obviously an XFS regression as the problem is
that alloc_pages(GFP_KERNEL) is the new failure on .27. The fact
that XFS never handled the allocation failure is not a new bug
or regression - it has never caught failures during log
allocation...

So really, if you want to look for a regression here, it is the
change of behaviour in the VM leading to a memory allocation failure
where it has never, ever previously failed...

Cheers,

Dave.
