Without this modification:
# dtrace -n 'syscall:::entry { @[execname, probefunc] = count(); }' -c "echo hello"
dtrace: invalid probe specifier syscall:::entry { @[execname, probefunc] = count(); }: "/usr/lib/dtrace/ipfw.d", line 1: cached_id is not a member of struct ip_fw(Is "line 1" here also a bug?)
I didn't change the field names in ipfw_rule_info for compatibility, but if it
is ok to change, I would like to rename them to cache_id and cache_pos.
Proposed commit message:
