I thought this all sounded familiar. It surfaced a couple of years ago, and this was my summary of the intent at the time: http://lkml.indiana.edu/hypermail/linux/kernel/0609.1/2106.html It all went round and round for a while, but I don't think anything got merged. In fact I can't even find Ben's original little spufs/cell NOPAGE_RETRY code in the tree, an I thought we merged that. Confused. The questions are, of course: does this new code address the issues which were raised at that time? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
