Subject: [RFC PATCH 0/7] tracing: Use common error_log with probe events
Date: Wed, 13 Mar 2019 21:27:32 +0900 [thread overview]
Message-ID: <155248005229.10815.334731901778152247.stgit@devnote2> (raw)
Hi Tom,
Here is a series of patches which applies common error_log framework to
probe events. While applying it, I found I missed to check some errors
in parser. Also, I made a testcase for this feature (only for kprobe
event side, please make your test for the hist errors too).
Thus I made this as a series which contains some bugfixes (a kind of
hardening), cleanups, and a test besides of the main patch.
Please feel free to pick this series to your series. I think some
bugfixes might be better to push Steve's urgent branch.
Let's talk with Steve.
Oh, note that this series can be applied on your v3 series, except
for [4/5] :)
Thank you,
