Merge tag 'wq-for-6.8-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue fix from Tejun Heo:
"Just one patch to revert commit ca10d851b9ad ("workqueue: Override
implicit ordered attribute in workqueue_apply_unbound_cpumask()").
This commit could break ordering guarantees for ordered workqueues.
The problem that the commit tried to resolve partially - making
ordered workqueues follow unbound cpumask - is fully solved in
wq/for-6.9 branch"
* tag 'wq-for-6.8-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq:
