[dm-devel] [PATCH 27/78] kpartx.rules: Skip kpartx for multipath events

[Hannes Reinecke]

Whenever multipath signals a PATH_FAILED or PATH_REINSTATED
event we don't have to call 'kpartx'; the contents on the disk
haven't changed.
And we should never call kpartx if all paths are down, irrespective
of the uevent.
