Subject: [PATCH v3 5/8] io_uring: convert io_uring to the secure anon inode interface
Date: Mon, 13 Sep 2021 23:33:22 -0400	[thread overview]
Message-ID: <163159040254.470089.7192304410101378968.stgit@olly> (raw)
In-Reply-To: <163159032713.470089.11728103630366176255.stgit@olly>

Converting io_uring's anonymous inode to the secure anon inode API
enables LSMs to enforce policy on the io_uring anonymous inodes if
they chose to do so.  This is an important first step towards
providing the necessary mechanisms so that LSMs can apply security
policy to io_uring operations.
