Cover letter [RFC 0/2] raid5 trim support
These are the raid5 trim support patches I'm working on. There are some limitations to support raid5 trim. I explained the details in the first patch. The raid5 state machine is quite complicated and I'm sure I missed something, so it's a RFC so far. And the raid5 trim suffers from the same discard request merge issue as raid0/10. If you try these in a SSD, please ignore the warning from block layer. But anyway, my raid4/5/6 tests work well with a fusionio card. Comments and suggestions are welcome!
Thanks,
Shaohua
