[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 3/5] build: Alloc space for sched list in the link file
Creates a section to contain scheduler entry pointers that are gathered together into an array. This will allow, in a follow-on patch, scheduler entries to be automatically gathered together into the array for automatic parsing.
