[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 1/5] monitor: Rename vm_event_monitor_get_capabilities
The monitor_get_capabilities check actually belongs to the monitor subsystem so
relocating and renaming it to sanitize the code's name and location. Mechanical
patch, no code changes introduced.
