This patch set is has multiple parts.
patch 01 is just a resubmit of my previous patch, with Martin's
corrections added.
Patches 02 - 06 are miscellaneous fixes and cleanups
Patches 07 - 09 are related to adding a new format wildcard, at the
request of HPE, that allows multipath to get and display
information from the vendor specific VPD pages
Patches 10 - 15 are the part that needs the most review, patch 14
especially. It turns out that on machines with a large number
of cores, io_destroy(), which is used by the directio checker,
can take a long time to complete. Talking to some kernel people
at Red Hat, I was told that this isn't a bug. It's working as
expected, and multipath shouldn't be issuing so many
io_destroy() calls (1 per path, when multipath or multipathd
stops). Cutting out the io_destroy calls involved a major change
to the directio checker. It's pretty hard to test a lot of the
corner cases on actual hardware, so I've written a bunch of
unit tests for this (patch 15).
