[libvirt] [PATCH 02/12] Convert virDomainVcpuPinDefPtr to virDomainPinDefPtr
John Ferlan

Sat Mar 14 03:11:46 UTC 2015
As pointed out by jtomko in his review of the IOThreads pinning code:
http://www.redhat.com/archives/libvir-list/2015-March/msg00495.html
there are some comments sprinkled in indicating IOThreads were using
the same structure as the VcpuPin code...
This is the first patch of a few that will change the virDomainVcpuPin*
structures and code to just virDomainPin* - starting with the data
structure naming...
