From 60bbddaaa33865633efa2800702e3b02495a0e94 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 7 May 2012 14:09:00 +0900 Subject: perf target: Introduce perf_target_errno The perf_target_errno enumerations are used to indicate specific error cases on perf target operations. It'd help libperf being a more generic library.
