| |
This patchset contains bindings for the kernel workqueue.
One of the primary goals behind the design used in this patch is that we must support embedding the `work_struct` as a field in user-provided types, because this allows you to submit things to the workqueue without having to allocate, making the submission infallible. If we didn't have to support this, then the patch would be much simpler. One of the main things that make it complicated is that we must ensure that the function pointer in the `work_struct` is compatible with the struct it is contained within.
The original version of the workqueue bindings was written by Wedson, but I have rewritten much of it so that it uses the pin-init infrastructure and can be used with containers other than `Arc`.
Changes since v1:
Most of this patchset was rewritten based on Gary's example for how field projections can be used with the workqueue.
I have also added some examples of how the workqueue bindings will be used. You can find those in the last patch of this patchset.
