I'm trying to compile an open source driver for my new USB Rosewill RNX-MiniN2 wireless adapter, and I'm running into the following error:

Evidently, due to recent kernel changes, smp_lock.h doesn't exist anymore.

How can I kludge this together and make it work? I just paid for this USB stick and I'd like to be able to use it and not have to ship it back.

Just needed to create a fake smp_lock.h file in /usr/src/linux-headers-$(uname -r)/include/linux/:

sudo touch "/usr/src/linux-headers-$(uname -r)/include/linux/smp_lock.h

It works!
