I think this is fine and should be kept until
some general agreement is made that OOM messages
should be removed generically.

If these are really superfluous, which I doubt a
little because these are emitted at different
KERN_<LEVEL>, (the generic one emits at KERN_WARNING),
there are _thousands_ of these OOM errors in drivers/
alone that could be removed.

$ grep -rP --include=*.[ch] \
"(printk|\b[a-z]+_\w+)\s*\(.*\".*(alloc|mem)" drivers | \
wc -l
5147

call it 50% false positive, it's still a lot.

I think one more won't hurt for awhile.
