Hello, Linus.
Sorry about the late pull request. I forgot to send them out before
the holidays.
This pull request contains fixes for the following two non-trivial
issues.
* The task iterator got broken while adding thread mode support for
v4.14. It was less visible because it only triggers when both
cgroup1 and cgroup2 hierarchies are in use. The recent versions of
systemd uses cgroup2 for process management even when cgroup1 is
used for resource control exposing this issue.
* cpuset CPU hotplug path could deadlock when racing against exits.
There also are two patches to replace unlimited strcpy() usages with
strlcpy().
Thanks.
