Subject: [RFC PATCH 0/8] nvmet: implement target passthru commands support
Date: Fri, 30 Mar 2018 02:57:39 -0400 [thread overview]
Message-ID: <20180330065747.20962-1-chaitanya.kulkarni@wdc.com> (raw)
Hi,
This patchset implements NVMeOF target passthrough commands support.
In current implementation on the target side, NVMe command is mapped on the
block layer request which allows the target to use generic block device.
With the help of passthrough interface, it can now identify the NVMe controller
and allow the host to issue NVMe commands along with the VUCs on the
target side. For example with this feature, depending on the target controller
support host can issue namespace management commands,
Vendor unique commands etc.
The code is tested on the loopback target (nvme-loop) and cut against
the Linux 4.16-rc7 (tag v4.16-rc7).
Regards,
Chaitanya
