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:

TUrns out I pulled it into the wrong branch. But even after correcting
that, I now see:

which is still off, with the discrepancy being in raid5.c?

Hmm... I just pulled your for-5.20/drivers branch again, and I am still getting the 
original diff:

Is is because different git versions? My current version is git version 2.30.2. 

Thanks,
