From: Adrian Hunter Date: Mon, 17 Feb 2020 08:23:00 +0000 (+0200) Subject: perf auxtrace: Add auxtrace_record__read_finish() X-Git-Tag: v5.15~4389^2~1^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ad60ba0c2e6da6ff573c5ac57708fbc443bbb473;p=platform%2Fkernel%2Flinux-starfive.git perf auxtrace: Add auxtrace_record__read_finish() All ->read_finish() implementations are doing the same thing. Add a helper function so that they can share the same implementation.
