The original patchset is available here: https://lkml.org/lkml/2019/6/21/419

We wanted to wait posting our updated patches until the base patches 
were upstream. I guess the cat is out of the bag. :)

For the open/finish/reset patch, you'll want to take a look at the 
original patchset, and apply the feedback from that thread to your 
patch. Please also consider the users of these operations, e.g., dm, 
scsi, null_blk, etc. The original patchset has patches for that.
