Module Name:    src
Committed By:   jdolecek

Modified Files:
        src/sys/kern: kern_event.c

Log Message:
call f_touch with kq_lock held, and without KERNEL_LOCK() - for this
adjust EVFILT_USER, which is the only filter actually using that hook

kqueue_scan() now doesn't need to exit/enter the kq_lock when calling
f_touch, which removes another possible race
