Description of problem:
The <workqueue.h> kernel header is the 2.5 version, but kernel/workqueue.c
does not exist! I don't know if reverting this file breaks anything else, and
I haven't tried it yet, but using the 2.5 version defines several macros that
are used as indicators in ALSA of a kernel with 2.5 style workqueuing, which
this kernel does not have. ALSA has a workaround, but it will not enable if it
thinks the kernel has support for it. This means that when one compiles the
alsa-driver package, module snd.o always fails to insert, because it is
missing the symbol schedule_work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Get redhat-9.
2. Get alsa-driver-0.9.x
3. Untar it, run configure w/whatever options - it makes no difference, and
4. make install and attempt to modprobe snd - it fails.
Actual Results: It failed.
Expected Results: It should have inserted.
