This cover letter is only there to draw attention on the fact that I'm a bit unsure about the use of GFP_KERNEL in 'kbuf_alloc_2_sgl()'. In all conversion that I've done, GFP_USER was never used. I don't fully understand the difference between GFP_USER and GFP_KERNEL. So please review with care. For the 3 other functions, I'm much more confident. I've put the explanation of why I think that GFP_KERNEL is safe in patch 1/1. Basically, these functions already call some functions that can sleep.
