bio_alloc will not fail when __GFP_WAIT is specified in the gfp_flags. See
http://lkml.org/lkml/2009/4/14/198 for the discussion. But this not documented
and there are places where there is unwanted code to handle bio_alloc failure
even when __GFP_WAIT is specified. This patch set documents this and cleans up
various callers who assume bio_alloc can fail even with __GFP_WAIT.
Thanks

I added your patches 2-7, I substituted 1/7 with one I did myself that
uses proper kerneldoc annotation. Thanks!
