Subject: [PATCH] multipathd: make pr registration consistent
multipathd was inconsistent on what it did with persistent reservations
when a multipath device was created. If a multipath device with a
configured reservation key was created during configure(), multipathd
would try to read the registered keys using an active path. If it saw a
matching key, it would set the prflag, but not attempt to register the
key on any of the other paths. This means that if a new path had
appeared while multipathd was not running, it wouldn't register the key
on this path.
If the multipath device was created during ev_add_path(), multipathd
would used the added path to check if there was a matching key and if
there was, register the key only on the added path and then set the
prflag. This could be problematic if the device was created with
multiple paths, for instance because find_mutipaths was set to "yes" and
a second path just appeared. In this case, if the device happened to be
only registered on the second path, it would not get registered on the
first path.
If the multipath device was added to multipathd during a call to
ev_add_map(), multipathd wouldn't set the prflag or register the key on
any paths.
After a device was created with the prflag set, if a new path appeared
before the creation uevent, and multipathd was forced to delay adding
it, when it finally updated the multipath device, the key would be
registered on all paths, fixing any paths missed during creation.
However, if a new path appeared after the creation uevent, the key would
only be registered on that new path. Any paths that were missed on
creation would stay missed.
persistent key registration needs to be handled consistently. This
patch does so by making sure that however a multipath device is added to
multipathd, it will check to see if the configured key is registered. If
it is, multipathd will set the prflag and register the key on all the
currently active paths.
When a new path is added, multipathd will use it to check for active
keys, as before. But if it finds a matching key and prflag isn't
currently set, it will register the key on all paths.

Subject: [PATCH] multipathd: handle no active paths in update_map_pr
When a multipath device is first created, if it has a reservation key
configured, update_map_pr() will check for a matching key on the active
paths. If there were no active paths to check with, multipathd was
leaving mpp->prflag in PRFLAG_UNSET, as if there were no matching keys.
It's possible that when update_map_pr() is called, all the paths will be
in the PATH_PENDING state because the checkers haven't completed yet. In
this case, multipathd was treating the device as having no registered
keys without ever checking.
To solve this, multipath devices now start with prflag = PRFLAG_UNKNOWN.
It will remain in this state until multipathd actually tries to get the
registered keys down a path. If the map is in this state, it will check
newly active paths, and if it finds a matching key, it will register
the key down all active paths.
