pacemaker/pacemaker-NodeUtilization-RA.patch
Yan Gao 3b1daef8d4 - Rebase: 
* pacemaker-NodeUtilization-RA.patch
  * pacemaker-colocated-utilization.patch
- xml: Clean up schema list at exit
- pengine: Support cluster-specific instance attributes based on rules (FATE#316118)
- crmd: Ensure crm_config options are re-read on updates
- Resolve all clang analyser defects
- xml: Check all available schemas when doing upgrades
- Changes to the ACL schema to support nodes and unix groups
- tools: Allow crm_shadow to create older configuration versions
- xml: Prevent use-after-free when comparing two xml documents
- cib: Resolve memory leaks in query paths
- xml: Correctly subtract xml with v1 patchsets
- fencing: Advertise support for reboot/on/off in the metadata for legacy agents
- fencing: default to 'off' when agent does not advertise 'reboot' in metadata
- fencing: Execute all required fencing devices regardless of what topology level they are at
- fencing: Fence using all required devices
- fencing: fixed so that change of <resources> could be handled correctly.
