Additional debuggability, better optimised, better-enforced semantics, etc. Obviously, there are some places that can't be converted to mutexes. I'm not proposing blind changes. I've been through a dozen places and found some that can be converted to spinlocks, others to completions, but mostly to mutexes. So as not to lose these patches, I've made them available as a git tree. I think the right way to get these patches in will be to go through the maintainers of each file. I'll post a list of the places using semaphores later. My current list is a bit out of date and contains insulting comments that I would like to rephrase before the authors of the code in question see them ;-) http://git.kernel.org/?p=linux/kernel/git/willy/misc.git;a=shortlog;h=semaphore-removal Stephen, could you pick these patches up for linux-next? git://git.kernel.org/pub/scm/linux/kernel/git/willy/misc.git semaphore-removal -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step."
