Subject: [PATCH 1/5] fs: add file_operations->uring_cmd()
Date: Wed, 27 Jan 2021 14:25:37 -0700	[thread overview]
Message-ID: <20210127212541.88944-2-axboe@kernel.dk> (raw)
In-Reply-To: <20210127212541.88944-1-axboe@kernel.dk>

This is a file private handler, similar to ioctls but hopefully a lot
more sane and useful.
