Subject: [RFCv4 3/7] arm: perf: move to common attr_group fields
Date: Thu, 8 Sep 2016 11:21:48 +0100 [thread overview]
Message-ID: <1473330112-28528-4-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1473330112-28528-1-git-send-email-mark.rutland@arm.com>
By using a common attr_groups array, the common arm_pmu code can set up
common files (e.g. cpumask) for us in subsequent patches.
