Hi, again
i do not know whether it may be important, but the warning
makes me anyway curios.
In 2.4.3-ac13 the compiler says that init_rwsem in the
usbdevice_fs.h is redefined. It was previously defined in a .ver-file.
/*
* sigh. rwsemaphores do not (yet) work from modules
*/
#define rw_semaphore semaphore
#define init_rwsem init_MUTEX <<<<<<<<<<<<<<<< here
#define down_read down
#define down_write down
#define up_read up
#define up_write up
Should it be fixed? And, maybe the other define's around
should be fixed too?

P.S. the original warning (gcc-2.95.2):
In file included from hub.c:24:
linux-2.4.3-ac13/include/linux/usbdevice_fs.h:170: warning: `init_rwsem' redefined
linux-2.4.3-ac13/include/linux/modules/rwsem-spinlock.ver:2: warning: this is the location of the previous definition

The comment line above actually says it all. The defines
have been added because at the time of writing this file
rw semaphores did not work in a module, so they were
replaced with mutexes using these defines. If rw sems work
now just delete these defines
