Subject: [PATCH -tip v2 0/2] kprobes/x86: RO text code bugfix and cleanup
Date: Sat, 12 Aug 2017 09:43:43 +0900	[thread overview]
Message-ID: <150249861299.18166.13400123503538960282.stgit@devbox> (raw)

Hi,

This series fixes a kprobe-x86 bug related to RO text and
cleans up addressof operators.

The first one is an obvious bug that misses to set memory
RO when the function fails. And the second one is just a
cleanup patch to remove addressof operators ("&") since
it is meaningless anymore.

V2 has just a following update:
 - [1/2] Use a helper variable instead of using p->ainsn.insn
   directly.

Thanks,

---
