[libvirt] [PATCH] Rename tunable event constants
Daniel P. Berrange

Thu Sep 25 16:51:15 UTC 2014
For the new VIR_DOMAIN_EVENT_ID_TUNABLE event we have a bunch of
constants added
VIR_DOMAIN_EVENT_CPUTUNE_<blah>
VIR_DOMAIN_EVENT_BLKDEVTUNE_<blah>
This naming convention is bad for two reasons
- There is no common prefix unique for the events to both
relate them, and distinguish them from other event
constants
- The values associated with the constants were chosen
to match the names used with virConnectGetAllDomainStats
so having EVENT in the constant name is not applicable in
that respect
This patch proposes renaming the constants to
VIR_DOMAIN_TUNABLE_CPU_<blah>
VIR_DOMAIN_TUNABLE_BLKDEV_<blah>
ie, given them a common VIR_DOMAIN_TUNABLE prefix.
