Subject: [PATCH v6 3/7] perf: define EVENT_DEFINE_RANGE_FORMAT_LITE helper
Date: Sun, 21 Dec 2014 23:48:48 -0800 [thread overview]
Message-ID: <1419234532-22657-4-git-send-email-sukadev@linux.vnet.ibm.com> (raw)
In-Reply-To: <1419234532-22657-1-git-send-email-sukadev@linux.vnet.ibm.com>
Define a lite version of the EVENT_DEFINE_RANGE_FORMAT() that avoids
defining helper functions for the bit-field ranges.
