I've pushed out a new version of the trim patchset:

http://git.kernel.org/?p=linux/kernel/git/willy/ssd.git;a=shortlog;h=trim-20090309

Now that the ATA bits don't rely on the SCSI bits, I've rearranged the
SCSI bits to be last (since we seem to be closer to having consensus
and shipping devices using TRIM than we do UNMAP).

After I've had a chance to do some testing with these patches, I'd like to
see the first five patches go upstream during the upcoming merge window,
probably through Jeff's IDE tree.

I'd also like the sixth and seventh patches to go upstream during that
merge window, since we also need Read Capacity 16 for 4k sector support,
but that is a different topic for a different thread.
