Here are a number of multipath patches. The first two are resends of the skip_kpartx patches that didn't get merged from my last patchset. I didn't see any complaints about them, so I just rebased them. If there are any questions or objections, please let me know. The third and ninth patches both deal with paths that change wwids while in use. Ususally this happens because of LUN remapping, which is not multipath's fault. However, not dealing with it can cause multipathd to crash. It's also nice to give users the chance to disable the device before it accidentally writes to the wrong LUN. The INIT_REQUESTED_UDEV code is currently broken, but my fix does mean that multipathd now grabs the vecs lock on all path change events. It did this for years, so I don't know it that is controversial or not. If it is I can probably work around it. The disable_changed_wwids also needs to grab the vecs lock on change events, but only if the user enables it (it's off by default).
