This patch series is to support io_uring iopoll feature
in scsi stack. This patch set requires shared hosttag support.

This patch set is created on top of 5.12/scsi-staging branch.
https://kernel.googlesource.com/pub/scm/linux/kernel/git/mkp/scsi/+/refs/heads/5.12/scsi-staging

Resend this series as I have to rebase it to 5.12/scsi-staging.

v2 -> 
- updated feedback from v1.
- add reviewed-by & tested-by tag
- remove flood of prints in scsi_debug driver during iopoll
  reported by Douglas Gilbert.
- added new patch to support to get shost from hctx.
  added new helper function "scsi_init_hctx"

v1 -> 
Fixed warnings in scsi_debug driver.
Reported-by: kernel test robot <lkp@intel.com>
