How about

resource_ctl

?

resource_control/ is kinda long-ish and the other names we have there
are nice and short, see below.

BTW, while we're talking renaming, I have a patch which renames the MCE
pile and am planning to slap it in around -rc6 timeframe since we don't
have a lot of RAS commits this time around, see also the end of this
mail. It makes the naming there all nicely regular. :)

Sure, I can do that together with the directory rename once we've agreed
on the name.

Thx.

Subject: [PATCH] x86/mce: Streamline MCE subsystem's naming

Rename the containing folder to "mce" which is the most widespread name.
Drop the "mce[-_]" filename prefix of some compilation units (while
others don't have it).

This unifies the file naming in the MCE subsystem:

mce/
|-- amd.c
|-- apei.c
|-- core.c
|-- dev-mcelog.c
|-- genpool.c
|-- inject.c
|-- intel.c
|-- internal.h
|-- Makefile
|-- p5.c
|-- severity.c
|-- therm_throt.c
|-- threshold.c
`-- winchip.c

No functional changes.
