virtiofs: Add support for SELinux
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2101526
Upstream Status: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/


Signed-off-by: Vivek Goyal <vgoyal@redhat.com>

Patches backported from upstream and these applied with some fuzz but no failures. Built a kernel and tested it with SELinux enabled with virtiofs. Ran a modified version of SELinux test suite to run filesystem tests on virtiofs and it passed.
