Patches 1-3 fix "[Bug #11903] regression: vmalloc easily fail", and these should go upstream for 2.6.28. They've been tested and shown to fix the problem, and I've tested them here on my XFS stress test as well. The off-by-one bug, I tested and verified in a userspace test harness (it doesn't actually cause any corruption, but just suboptimal use of space). Patches 4,5 are improvements to information exported to user. Not very risky, but not urgent either. Patches 6-9 improve locking, guard page scheme, put guard pages under CONFIG_DEBUG_PAGEALLOC, and add a non-lazy-flush mode for CONFIG_DEBUG_PAGEALLOC to catch use-after-free better. These are more intrusive improvements. I'd like to see them merged, but they can happily wait for next merge window. Andrew, it's probably best if you take care of sending these upstream?
