Modified files:
sys/kern kern_mutex.c
sys/sys mutex.h
Log:
Cache the value of curthread in the _get_sleep_lock() and _get_spin_lock()
macros and pass the value to the associated _mtx_*() functions to avoid
more curthread dereferences in the function implementations. This provided
a very modest perf improvement in some benchmarks.
