[PATCH V2 0/6] nvme-core: timeout related fixes and cleanup

[Chaitanya Kulkarni]

Hi,

This patch series uses NVME_IO_TIMEOUT for the sync request submission
and user request submission when the timeout is not specified by the caller
and request queue data is set to NULL which is true for admin queue.

Also in this version, I've added timeout values setting for the NVMeOF
passthru controller given that passthru VUCs (both admin and I/O VUCs)
can differ in execution time than general-purpose admin and I/O command
set.

The last patch is just my personal preference, feel free to ignore it.

Regards,
Chaitanya

* Changes from V1:-

1. Instead of using qid to decide IO or ADMIN timeout use request
   queue's queuedata whch we only set for non admin queue
   __nvme_submit_sync_cmd().
2. Add second patch to set IO timeout for nvme_submit_user_cmd().
3. Set the NVMeOF passthru ctrl timeout values with default values from
   nvme-core module.
4. Add admin and I/O timeout configfs attributes for NVMeOF passthru
   controller.

Chaitanya Kulkarni (6):
  nvme-core: use I/O timeout in submit sync cmd
  nvme-core: use I/O timeout in nvme_submit_user_cmd
  nvmet: set default timeout for passthru requests
  nvmet: add passthru admin timeout value attr
  nvmet: add passthru io timeout value attr
  nvme: use consistent macro name for timeout
