hm, if you say so. The description in that patch is nowhere near complete
enough for me to be able to work out what it does.
The sys_sched_yield() is particularly incomprehensible and needs good
commenting. You are, I hope, aware of the severe problems which yield()
causes when the system is busy? The process which calls it will get
practically no CPU at all.
Minor point: that patch has several unneded (and undesirable) casts of void*:
+static void acpi_os_execute_notify(void *context)
+{
+ struct acpi_os_dpc *dpc = (struct acpi_os_dpc *)context;
please remove those.
