[PATCH 0/2] nvme: add command retry driver control flag

[Minwoo Im]

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,
