Subject: [PATCH 09/15] linux: Add fsmount
Date: Thu, 3 Feb 2022 14:46:28 -0300 [thread overview]
Message-ID: <20220203174634.3474775-10-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20220203174634.3474775-1-adhemerval.zanella@linaro.org>
It was added on 5.2 (93766fbd2696c2c4453dd8e1070977e9cd4e6b6d) to
provide a way by which a filesystem opened with fsopen and configured
by a series of fsconfig calls can have a detached mount object
created for it.
