kernel module must cope with removal of init_MUTEX in 2.6.37 #48

Closed GoogleCodeExporter closed 9 years ago

https://patchwork.kernel.org/patch/291752/ made the change.

If we are only using a sema as a big kbus lock, we probably ought to be using a 
mutex instead. (http://lwn.net/Articles/165039/ refers; it looks like Ingo 
Molnar's work which was accepted.) I have a tentative patch to do this in my 
mainline test repo.

This was done and pushed to the kernel repo in what became hg id 001bf4df51a3.

FAOD the fix is compatible with many kernels before 2.6.37 as it uses the mutex 
support which has been around since 2005.
