the current alsa code checks the existence of __WORK_INITIALIZER
macro.  if it's defined, no wrapper function is used.
in rh's include/linux/workqueue.h, is this macro defined?


btw, alsa-devel is the suitable place for such a problem.
i added a cc.


ciao,

Takashi

Yes, it is... from /usr/src/linux-2.4.20-x/include/linux/workqueue.h:

#define __WORK_INITIALIZER(n, f, d) {                           \
        .entry  = { &(n).entry, &(n).entry },                   \
        .func = (f),                                            \
        .data = (d) }

hmm, then it should be ok.  the configure and make should work without
any patches.

did anyone build successfully with RH9 and RH's kernel?
