[PATCH v3 03/24] multipath-tools: decrease verbosity of state messages

[Martin Wilck <mwilck@suse.com>]

With verbosity level 3, thousands of "path state = running" messages
are logged, which are pretty much irrelevant, as the checker state
takes precedence. Also the "get_state" message is totally useless.

With this patch, the path state is reported exactly once per path
and check.
