Hi,

this is not actually right though... sk_allocation is very possible to
have a restricting mask compared to the one passed in (say "no highmem"
or even GFP_DMA) and you now discard this... probably better would be to
calculate a set of "transient" flags that you then or into the
sk_allocation mask at this time...

Greetings,
