[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 10/29] xl: split out xl_parse.[ch]
Move all parsing code into xl_parse.c. Export the ones needed in
xl_parse.h.
Some notable changes other than code movement:
1. rename cpurange_parse to parse_cpurange;
2. provide a function to return shutdown action name.
