Subject: [PATCH 0/2] nvme: add command retry driver control flag
Date: Mon, 15 Feb 2021 22:05:52 +0900 [thread overview]
Message-ID: <20210215130554.32387-1-minwoo.im.dev@gmail.com> (raw)
Hello,
This series is to support command retry for passthru commands via ioctl.
This patch introduced `driver_ctrl` flag to the passthru ioctl command
structures by replacing the existing `rsvd` field with `driver_ctrl`
flag.
This flag can be used to give some control flag to the driver from
user-space. The first flag introduced in this series is
`NVME_DRIVER_CTRL_RETRY` to make command retry-able in failure case
without DNR status. (And of course, in case it's not a path-related
errors).
Please have a look.
Thanks,
