commit b4deb7beb8c977f79642a6a839c0475e1ce3a209
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jan 31 09:46:24 2022 -0300
linux: Add fsmount
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.
