After the first send, I realized I had missed some greybus-specific maintainers, so I resent to include them all. Then that should have been a v2 patch :) > For the indentation: You're right to ask about it. When I changed the declaration from 'char *envp[]' to 'static const char * const envp[]', the opening bracket moved to the right due to the longer declaration. I added tabs to keep the array elements aligned with the opening bracket, following the kernel coding style rule that parameters should align with the opening parenthesis. > > If this alignment approach is not preferred, I'm happy to adjust it to whatever style you recommend. You did not document your change, and it had nothing really to do with the const change, so I would not recommend doing this. Also, please do not top-post, and be sure to properly wrap your lines in your email client. thanks, greg k-h

[PATCH] drivers/greybus: add WQ_PERCPU to alloc_workqueue users

by Marco Crivellari

Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. 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") This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. 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. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default.
