Subject: [PATCH v2 3/3] x86/kprobes: Remove unneeded arch_within_kprobe_blacklist from x86
Date: Mon, 17 Dec 2018 17:21:53 +0900 [thread overview]
Message-ID: <154503491354.26176.13903264647254766066.stgit@devbox> (raw)
In-Reply-To: <154503482486.26176.6224515860220847638.stgit@devbox>
Remove x86 specific arch_within_kprobe_blacklist().
Since we have already added all blacklisted symbols to
kprobe blacklist by arch_populate_kprobe_blacklist(),
we don't need arch_within_kprobe_blacklist() on x86
anymore.
