I hope they don't use it with GFP_ATOMIC, either, because it's never been 
respected in that context.  We can easily audit the handful of cases in 
the kernel that use __GFP_NOFAIL (it takes five minutes at the max) and 
prove that none use it with GFP_ATOMIC or GFP_NOFS.  We don't need to add 
multitudes of warnings about using a deprecated flag with ludicrous 
combinations (does anyone really expect GFP_ATOMIC | __GFP_NOFAIL to work 
gracefully)?
