This release aims to address all pending review items including MD bug fixes and async_tx api changes from Neil, and concerns on channel management from Chris and others. Data integrity tests using home grown scripts and 'iozone -V' are passing. I am open to suggestions for additional testing criteria. I have also verified that git bisect is not broken by this set. The short log below highlights the most recent changes. The patches will be sent as a reply to this message, and they are also available via git: git pull git://lost.foo-projects.org/~dwillia2/git/iop md-accel-linus Additional comments and feedback welcome.
