Hi Jens, 

Please consider pulling the following changes for md-next on top of your
for-5.20/drivers-post branch. The major change is:

1. Fix potential deadlock with raid5_quiesce and and raid5_get_active_stripe, 
   by Logan Gunthorpe. 

This pull request was delayed because of some pending discussion [1]. Since
the discussion is more about code readability, I suggest we ship the fix now, 
and address the readability concern later. 

Thanks,
Song
