Hello.
So you don't want to add __GFP_NORETRY and __GFP_NOWARN for kmemcheck?
I think that it isn't good idea, since users would meet *unexpected*
allocation failure if they enable kmemcheck and slub uses different flags
for kmemcheck. It makes users who want to debug their own problems embarrass.
Thanks.
