| |
It's been a Good Idea for a while to use mutexes instead of semaphores where possible. 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 My current list is a bit out of date and contains insulting comments that I would like to rephrase before the authors of the code in question see them ;-)

Stephen, could you pick these patches up for linux-next?
