Hey,
people are asking for comments on 2.5.x, so here goes. gcc-2.96, RH-7.3,
kernel 2.5.66 with module-init-tools-0.9.10.
* the smc-ultra networking module doesn't work. On any operation, it
returns "Device or Resource Busy".
* module_request() is still broken - it returns 0 but the specified
module isn't loaded
Now, something more problematic. I'm being told to use try_module_get()
instead of MOD_INC_USE_COUNT. Cool. Somehow, it returns 1. I had a look
at the code in linux/module.h and am a bit confused:
--
static inline int try_module_get(struct module *module)
{
int ret = 1;
if (module) {
unsigned int cpu = get_cpu();
if (likely(module_is_live(module)))
local_inc(&module->ref[cpu].count);
else
ret = 0;
put_cpu();
}
return ret;
}
--
Why does it only return 0 if the module is not alive? This sounds...
er... weird? Can someone please enlighten me?
Looking further:
--
/* Not Yet Implemented */
#define MODULE_AUTHOR(name)
#define MODULE_DESCRIPTION(desc)
#define MODULE_SUPPORTED_DEVICE(name)
#define MODULE_PARM_DESC(var,desc)
--
No wonder modinfo doesn't show any info... Even worse, the only module
parameter thing that *does* work is MODULE_PARM...
--
/* DEPRECATED: Do not use. */
#define MODULE_PARM(var,type) \
struct obsolete_modparm __parm_##var \
__attribute__((section("__obsparm"))) \
{ __stringify(var), type };
--
Interesting. What's going on here?
