名称描述
kprobe_add_area_blacklistAdd all symbols in given area into kprobe blacklist
populate_kprobe_blacklistLookup and populate the kprobe_blacklist.* Unlike the kretprobe blacklist, we'll need to determine* the range of addresses that belong to the said functions,* since a kprobe need not necessarily be at the beginning* of a function.
