[PATCH RFC 0/2] workqueue: Make alloc_workqueue() unbound by default

[Marco Crivellari]

Hi,

This is a proposed change about the defualt behavior of alloc_workqueue().
Currently we enforce the use of WQ_PERCPU or WQ_UNBOUND. The pourpose of
this change is make the default behavior unbound so that calling
alloc_workqueue() without WQ_PERCPU results in an unbound workqueue.

After this step it would be possible remove WQ_UNBOUND from every
alloc_workqueue().

I tested the code with a small crafted driver, and to me it looks good.
Do you spot something I'm missed?

Thanks!
