Warner,

Is it going to be possible to MFC the NCQ trim fixes, or is this 
dependent on post 10.x work?

It took a longgggg time for Linux to catch up with Crucial's firmware 
patch. [1]

cheers
Bruce

[1] Which, by the way, is an excellent example of vendors doing the 
right thing for a change, as the patch was delivered as a Linux-based 
self-booting image (ISO/USB/etc).
