I'm trying to port drivers for rtl8191su and one problem is that build complains about missing init_MUTEX.
it's supposed to be in include/linux/semaphore.h, but it's not there.
I can see references to the function here and there in the code though.
is it declared somewhere else?
I'm using trunk/build_dir/linux-brcm47xx/linux-2.6.37/ for kernel sources dir.

thanks!
Andrey
