    Subject[PATCH 0/7] Cleanup code that think bio_alloc with __GFP_WAIT can fail
    Date
    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
    Nikanth
