You were CCed and provided very useful feedback: http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/01291.html Based on your feedback I re-spun them but never gotten around to port them to recent kernel and post them. The latest (yet unpublished versions) are here: https://github.com/gby/linux/commit/04e041327036772383c14ebdc450f522d782f264 https://github.com/gby/linux/commit/f5b8ae815670a289af9ff22ad83da3295472e63c I'll try to resurrect them, but maybe they'll prove useful as a reference as they are in the meantime.
