Subject: [RFC] fix slub krealloc()
Commit ef2ad80c7d255ed0449eda947c2d700635b7e0f5 breaks
krealloc(NULL, ...) badly, it BUG_ON()s.
This patch fixes it but the fix should probably be in mm/util.c because
the documentation says that krealloc(NULL, x, gfp) is equivalent to
kmalloc(x, gfp) and that's not true any more even after this patch when
you do krealloc(NULL, 0, gfp)
