From: Namhyung Kim Date: Wed, 6 Feb 2013 05:57:16 +0000 (+0900) Subject: perf sort: Make setup_sorting returns an error code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=553099857702bb77e541c47bde47f6863834d2e2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git perf sort: Make setup_sorting returns an error code Currently the setup_sorting() is called for parsing sort keys and exits if it failed to add the sort key. As it's included in libperf it'd be better returning an error code rather than exiting application inside of the library.
