Hello, I was looking at the linuxkpi locks and notice something that I don't understand. For linux struct mutex we use or sx locks but looking at the doc in linux (Documentation/locking/mutex-design.rst) it seems that those are almost 1:1 our mtx, is there a reason that sx where chosen ? For the linux spinlocks we use MTX_DEF lock, which doesn't seems right at all so same question. Thanks for your answers, -- Emmanuel Vadot <manu@bidouilliste.com> <manu@freebsd.org>
