[libvirt] [PATCH v2 06/20] virlog: Introduce virLogDefineFilters

Thu Aug 18 11:47:05 UTC 2016


Prepare a method that only defines a set of filters. It takes a list of
filters, preferably created by virLogParseFilters. The original set of filters
is reset and replaced by the new user-provided set of filters.
