| |
Hello,
Another follow-up fix. I missed a dummy implementation leading to bulid failure on s390. Because the bug and fix are trivial, I directly applied the patch to cgroup/for-4.15. Please let me know if it should be routed differently.
Thanks. ------ 8< ------ From 8157a7faf94135386bf04b1cf94e6efd3fb94702 Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Mon, 25 Sep 2017 14:27:54 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
cfb766da54d9 ("sched/cputime: Expose cputime_adjust()") made cputime_adjust() public for cgroup basic cpu stat support; however, the commit forgot to add a dummy implementaiton for CONFIG_VIRT_CPU_ACCOUNTING_NATIVE leading to compiler errors on some s390 configurations.
Fix it by adding the missing dummy implementation.
