That's exactly what you need to explain in the patch or the commit message. In fact you still haven't explained it fully. Why do we need a second attempt without the GFP_NOFAIL? How does it help the allocator? Cheers, -- Email: Herbert Xu <herb...@gondor.apana.org.au> Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
