Modified files:
sys/kern kern_mutex.c kern_rwlock.c kern_sx.c
Log:
Adjust td_locks for non-spin mutexes, rwlocks, and sx locks so that it is
a count of all non-spin locks, not just lockmgr locks. This can give us a
much cheaper way to see if we have any locks held (such as when returning
to userland via userret()) without requiring WITNESS.
