From 177629c34ed8345b561c7f04a3698981d4df5f0a Mon Sep 17 00:00:00 2001 From: Antique Date: Thu, 26 Apr 2018 12:37:35 +0200 Subject: [PATCH] cgroup-util: fix enabling of controllers (#8816) If enabling controller for some reason fails we need to clear error for the FILE stream. Enabling remaining controllers would otherwise fail because write_string_stream_ts() checks for ferror(f) and returns -EIO if there is one. Broken by commit <77fa610b22>.
