Re: [PATCH v8 01/13] arch/resctrl: Start renaming the rdt files to more generic names

[Borislav Petkov]

Just to state it here on the thread: prefix should be "x86/resctrl" as
we said earlier. But that will be addressed in the next iteration, as we
agreed offlist.

Ok, looking at this more, it looks like this:

ls -l arch/x86/kernel/cpu/resctrl*
 arch/x86/kernel/cpu/resctrl.c
 arch/x86/kernel/cpu/resctrl_ctrlmondata.c
 arch/x86/kernel/cpu/resctrl.h
 arch/x86/kernel/cpu/resctrl_monitor.c
 arch/x86/kernel/cpu/resctrl_pseudo_lock.c
 arch/x86/kernel/cpu/resctrl_pseudo_lock_event.h
 arch/x86/kernel/cpu/resctrl_rdtgroup.c

Now, it looks to me like the whole resctrl thing begs for its own dir:

 arch/x86/kernel/cpu/resctrl/core.c
 arch/x86/kernel/cpu/resctrl/ctrlmondata.c
 arch/x86/kernel/cpu/resctrl/internal.h
 arch/x86/kernel/cpu/resctrl/monitor.c
 arch/x86/kernel/cpu/resctrl/pseudo_lock.c
 arch/x86/kernel/cpu/resctrl/pseudo_lock_event.h
 arch/x86/kernel/cpu/resctrl/rdtgroup.c

This way, the whole RDT machinery will be confined to its own directory.

Hmm.
