[PATCH 0/3] uring-passthrough for admin commands

[Kanchan Joshi]

During the review rounds and LSFMM, it emerged that uring-passthrough
for admin-commands will also be useful. So this series wires that up.

Prepared against for-next (linux-block) on top of
commit cef3f8e4ed04 (Merge branch 'for-5.19/block'...).

Patch 1 is prep.
Patch 2 adds new opcode for admin uring-passthrough, and enables it over
ns char device (/dev/ngXnY). It reuses the code of io-command
passthrough, with the only difference that commands are issued on admin
queue.

Patch 3 enables the same for controller char device (/dev/nvmeX).

Kanchan Joshi (3):
  nvme: helper for uring-passthrough checks
  nvme: enable uring-passthrough for admin commands
  nvme: admin command uring-passthrough on controller node
