Thanks! I'm planning on replacing __GFP_NOFAIL with a different flag that
will use all of the page allocator's capabilities (direct reclaim,
compaction for order > 0, and oom killer) but not loop forever. Existing
__GFP_NOFAIL callers can then do
do {
page = alloc_page(GFP_KERNEL | __GFP_KILLABLE);
} while (!page);
to duplicate the behavior of __GFP_NOFAIL until such time as
__GFP_KILLABLE can be removed as well. That's what I was planning for the
remaining instances in gfs2 during the second phase.
