Raw Blame History

From 7a813755269f00d7b815e819636841af991762c0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix: tools: crm_resource --cleanup
The new "failures only" mode of crm_resource --cleanup had multiple issues,
including not working without --resource specified, comparing a
user-provided interval string against a milliseconds interval, and
considering no interval specified as all intervals rather than 0
but only when clearing LRM history entries.
