Hi, I'm trying to backport a security fix involving the mount namespaces (in fs/pnode.c), and I'm wondering if anyone has a set of sanity checks (ideally in the form of a shell script) which they use to make sure nothing has broken with respect to mount --make-shared, et. al. I've really gotten spoiled with xfstests, and the mount namespaces code looks subtle and quick to anger, and I'd prefer to have something more substantial than "It builds! Release it to production!" :-) Thanks, - Ted
