Modified files:
sys/sys _mutex.h
Log:
Save 16 bytes per mutex if MUTEX_PROFILING is not defined.
MUTEX_PROFILING is in opt_global.h, so this does not introduce a risk of
variant structure sizes unless foreign kernel modules are used.
This saved 16 bytes per vnode and 16 bytes per vm object for a total of
4MB on a 2GB machine.
