* When per-cpu workqueue workers expire after sitting idle for too long, they used to wake up to the CPU that they're bound to to exit. This unfortunately could cause unwanted disturbances on CPUs isolated for e.g. RT applications. The worker exit path is restructured so that an existing worker is unbound from its CPU before being woken up for the last time, allowing it to migrate away from an isolated CPU for exiting. * A couple debug improvements. Watchdog dump is made more compact and workqueue now warns if used-after-free during the RCU grace period after destroy_workqueue(). -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCY/Ktfg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGUAyAQDAs8HXnn7HDHvmJKWga7OaG3x+LhgJ6k17B4TQ kUhX3QEAoVFB9YVX777rIBI+XgVVbjmgFP0SaRBCm8El8gUkUws= =WPMP -----END PGP SIGNATURE----- Merge tag 'wq-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue updates from Tejun Heo: - When per-cpu workqueue workers expire after sitting idle for too long, they used to wake up to the CPU that they're bound to in order to exit.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
