2.6.33-rc6: ext4 triggers warning about high order allocations
Hi!
I got this warning at boot with 2.6.33-rc6:

I have not noticed this warning previously on the same kernel, so it's not easily reproducible. The system functions fine after this: __GFP_NOWARN missing somewhere?

^^^^
it's the auto_da_alloc option, which optionally takes a =X argument. I think someone changed match_one() and broke it; auto_da_alloc is the default anyway, so you can just drop this for now.

I have removed
auto_da_allocoption, but still see a warning at boot:
Any chance you've still got it in an initrd or grub rootfs options, or similar?
if not, perhaps you can narrow it down to which filesystem & which mount option is triggering this.

Looks like this was the case: I rebuilt initrd and it's gone.
