Merge tag 'cgroup-for-7.3-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
- With local event accounting, a fork rejected by the pids controller
updated pids.events without notifying its pollers
- A cgroup selftest failed to compile with fortification enabled
because an O_TMPFILE open lacked its mode argument
* tag 'cgroup-for-7.3-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
cgroup/pids: Restore pids.events notifications in local mode
selftests: cgroup: give the O_TMPFILE open in get_temp_fd() a mode
