Martin K Peterson has the respective patches needed queued up on his tree
for v5.16:

https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=5.16/scsi-staging&id=e9d658c2175b95a8f091b12ddefb271683aeacd9

Would the last patch be sent once that gets to Linus?

Also curious why drop the last two patches instead just the last one for
now?
