Hi Jens, 

Please consider pulling the following changes on top of your for-5.20/drivers
branch. The major changes are:

1. Improve raid5 lock contention, by Logan Gunthorpe.
2. Misc fixes to raid5, by Logan Gunthorpe.
3. Fix race condition with md_reap_sync_thread(), by Guoqing Jiang.

I pulled this in, but what I pulled doesn't match this pull request.
There seems to be an extra patch in there, and diffstat doesn't match
what is in your email:
