335c508c1b6SJohn Baldwin# the KTR option.  The KTR_EXTEND option causes trace events to be generated
336c508c1b6SJohn Baldwin# as a string from snprintf rather than as a string and up to 5 argument
337c508c1b6SJohn Baldwin# pointers.  KTR_ENTRIES defines the number of entries in the circular trace
338c508c1b6SJohn Baldwin# buffer.  KTR_COMPILE defines the mask of events to compile into the kernel
339c508c1b6SJohn Baldwin# as defined by the KTR_* constants in <sys/ktr.h>.  KTR_MASK defines the
340c508c1b6SJohn Baldwin# initial value of the ktr_mask variable which determines at runtime what
