Quick raising of hands: is there anybody out there that expects to use unshare(CLONE_VM) right now? One of the reasons it was integrated was that I thought glibc wanted it for distros. Is disabling the CLONE_VM unsharing going to impact that?Linus
We are using namespace and filesystem unsharing for our common criteria certification work and would not be impacted by disabling of vm unsharing. -Janak - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
