Subject: [PATCH V5 4/8] perf/x86/intel: Reorganize attrs and is_visible
Date: Wed, 25 Oct 2023 13:16:22 -0700	[thread overview]
Message-ID: <20231025201626.3000228-4-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20231025201626.3000228-1-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

Some attrs and is_visible implementations are rather far away from one
another which makes the whole thing hard to interpret.

There are only two attribute groups which have both .attrs and
.is_visible, group_default and group_caps_lbr. Move them together.

No functional changes.
