Subject: [PATCH v2 25/33] include/linux/resctrl.h: Define fork and exit functions in a new header file
Date: Thu,  8 Sep 2016 02:57:19 -0700	[thread overview]
Message-ID: <1473328647-33116-26-git-send-email-fenghua.yu@intel.com> (raw)
In-Reply-To: <1473328647-33116-1-git-send-email-fenghua.yu@intel.com>

From: Fenghua Yu <fenghua.yu@intel.com>

A new header file is created in include/linux/resctrl.h. It contains
defintions of rdtgroup_fork and rdtgroup_exit for x86. The functions
are empty for other architectures.
