Subject: [PATCH 0/2] nvme: Support for fused NVME_IOCTL_SUBMIT_IO
Date: Tue, 5 Jan 2021 14:49:37 -0800 [thread overview]
Message-ID: <20210105224939.1336-1-clay.mayers@kioxia.com> (raw)
From: Clay Mayers <clay.mayers@kioxia.com>
Enables fused compare/write to be issued from user mode.
The first patch allows a pair of pass through requests
to be linked and submitted as a fused pair to the nvme
device queue. The second patch exposes it through an
nvme ioctl so a cmp/write can be issued from user mode.
There was a question regarding Linux support for this
functionality in nvme-cli. With these patches, that
would be possible.
