For this set where we just refactored I checked performance to assure we didn't go downhill but didn't save the results as deltas were in the noise. After this series lands we will look at introducing performance improvements again and at that time results from a full performance sweep will be included. For data integrity, 1 and 2 disk mirrors were ran overnight w/fio and crcr32 check - no issues. To assure other code paths execute as they did before was a little trickier without a unit test framework but for those cases I did modify/un-modify the code several times to follow various code paths and assure they're working as expected (ie bad blocks, etc) -Paul
