Re: [syzbot] [mm?] WARNING in xfs_init_fs_context

[Christoph Hellwig]

This looks like slub turning a < PAGE_SIZE allocation into a order > 0
folio allocation, which the page allocator then complains about.

We'll either need to make slab not propagate < PAGE_SIZE allocations
to order > 0 page allocation, or make the page allocator handle the
latter.

And XFS shouldn't need the NOFAIL allocation here, but this will break
things elsewhere as well.
