Subject: [PATCH v4 5/8] io_uring: convert io_uring to the secure anon inode interface
Date: Wed, 15 Sep 2021 12:49:50 -0400	[thread overview]
Message-ID: <163172459001.88001.17463922586800990358.stgit@olly> (raw)
In-Reply-To: <163172413301.88001.16054830862146685573.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.
