Merge tag 'wq-for-6.6-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue fixes from Tejun Heo:
- Fix access-after-free in pwq allocation error path
- Implicitly ordered unbound workqueues should lose the implicit
ordering if an attribute change which isn't compatible with ordered
operation is requested. However, attribute changes requested through
the sysfs interface weren't doing that leaving no way to override the
implicit ordering through the sysfs interface. Fix it.
- Other doc and misc updates
