Subject: [PATCH 0/4] [GIT PULL] tracing, kprobes: Fix kprobe symbol offset (for minus)
Date: Fri, 23 Mar 2018 18:13:11 -0400 [thread overview]
Message-ID: <20180323221311.405667933@goodmis.org> (raw)
Linus,
The documentation for kprobe events says that symbol offets can
take both a + and - sign to get to before and after the symbol address.
But in actuality, the code does not support the minus. This fixes
that issue, and adds a few more selftests to kprobe events.
Please pull the latest trace-v4.16-rc4 tree, which can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
