If you do this, include it unconditionally, otherwise it would be a source of continuous troubles, where people only build-test INVARIANTS kernels. Then you can (should ?) remove sys/_lock.h.

This break buildworld, _lock is still needed for struct lock_object.
Will update the diff when I have something that compiles.

I do not quite understand your problem, please take a look at sys/lock.h line 38.

I probably understand. You need to put sys/lock.h before sys/_mutex.h.

Directly include sys/lock.h
