From 135117aa4055e13cd7c47e61093b5f1a15901fb3 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 14 Apr 2022 12:06:58 +0300 Subject: [PATCH] selftests: cgroup: Make cg_create() use 0755 for permission instead of 0644 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit b09c2baa56347ae65795350dfcc633dedb1c2970 upstream. 0644 is an odd perm to create a cgroup which is a directory. Use the regular 0755 instead. This is necessary for euid switching test case.
