Subject: [PATCH 0/2] nvme: support I/O passthrough for multipath
Date: Sun, 14 Feb 2021 20:01:24 +0900 [thread overview]
Message-ID: <20210214110126.24023-1-minwoo.im.dev@gmail.com> (raw)
Hello,
This series is to support I/O passthrough for multipath I/O.
Currently driver exposes block device for the head namespace. Also, the
path will be decided by the driver with the I/O policy defined to the
actual hidden device based on ANA state. This means that userspace is not
allowed to I/O passthrough to a specified namespace target which is hidden
by the driver.
This series is to support passthrough to the namespace attached to a
controller regardless to ANA state (e.g., inaccessible) and decided path
by the driver.
Please review.
Thanks,
