I don't really like lockdep_sys_exit() in such a call, lockdep_sys_exit() is currently placed such that it will execute as the last C code before returning to user-space. Put it any earlier and you've got a window where people can leak a lock to userspace undetected. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
