[PATCH v2 0/3] replace uses of system_wq with system_percpu_wq, request alloc_workqueue to be per-cpu

[Marco Crivellari <marco.crivellari@suse.com>]

Hi,

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

   commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
   commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")

More information can be found at the link below:

	https://lore.kernel.org/all/20250221112003.1dSuoGyc@linutronix.de/

=== Changes introduced by this series ===

1) [P 1] Request alloc_workqueue() to be per-cpu if WQ_UNBOUND is not present

	The refactoring is going to alter the default behavior of
	alloc_workqueue() to be unbound by default.

	With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
	any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
	must now use WQ_PERCPU.

2) [P 2-3] 

	Workqueue users must be converted to the better named new workqueues with
	no intended behaviour changes:

   		system_wq -> system_percpu_wq
   		system_unbound_wq -> system_dfl_wq

	This way the old obsolete workqueues (system_wq, system_unbound_wq) can be
	removed in the future.


Thanks!
