I really don't see the point of new helpers; especially since one doesn't have to _have_ vfsmount to use the old ones and since we don't have a lot of users of each of those to start with. As for the apparmor and friends... I'm far past the point of trying to give them feedback, seeing how any such feedback is ignored, if not worse (the ugliness of some of the suggested kludges is bloody astonishing - e.g. some guy proposed to stuff a reference to vfsmount into task_struct, etc.) -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
