From: James Morse <james.morse@arm.com> maillist inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8T2RT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git/log/?h=mpam/... --------------------------- rdtgroup_init() needs exporting so that arch code can call it once it lives in core code. As this is one of the few functions we export, rename it to have the filesystems name. x86's arch code init functions for RDT need renaming (again) to avoid duplicate definitions.
