Hmmm, so you suggest a single patch that will do s/unsigned long/u32 and that will be followed with this patch (almost) as is. Right? Also, regarding the stable thing, we will surely not be able to backport it straight away. But we should get it backported for sure. @Greg: What all kernel versions you want this to be backported for? -- viresh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
