Merge tag 'wq-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

Pull workqueue updates from Tejun Heo:

 - Work items can now be disabled and enabled, and cancel_work_sync()
   and disable_work() can be called form atomic contexts for BH work
   items.

   This closes feature gap with tasklet and should allow converting all
   existing tasklet users to BH workqueues.

 - Improve pool sharing for unbound workqueues with strict affinity.

 - Misc changes including doc updates, improved debug annotations and
   cleanups.
