[PATCH -tip RFC 0/2] kprobes: introduce NOKPROBE_SYMBOL() and prohibit probing on .entry.text
Currently the blacklist is maintained by hand in kprobes.c
which is separated from the function definition and is hard
to catch up the kernel update.
To solve this issue, I've tried to implement new
NOKPROBE_SYMBOL() macro for making kprobe blacklist at
build time. Since the NOKPROBE_SYMBOL() macros can be placed
right after the function is defined, it is easy to maintain.
At this moment, I
