This is the patchset to support MD discard, which I refresh against latest
kernel. It's pretty straightforward for raid linear/0/1/10. The raid456 discard
support is tricky, please see the log in the patches for details.

Previously when I posted the patches out, people complain SATA SSD discard
request merge error. Now a patch to disable discard request merge is in Jens's
tree. We don't have this issue any more.

I've applied 1 to 5 (linear,raid0,raid1,raid10), though '1' will probably
need to go through Jens' tree.

The RAID5 changes need a bit more work as described in a separate email.

Thanks,
