I don't understand why this report has come to linuxppc-dev (the patch touches an arch/powerpc file, but none of the problems reported are in that file). You should put the .config on a web site somewhere and include the URL and you should not include the whole patch (these were all quite large) - people can find them given a tree and commit (like above). And you sent out 7 reports for the same patch! I approved this bunch, but will not (unless pressured) approve any more. This scatter gun automated approach is like the boy crying wolf. I appreciate the effort, but please tone down the reports considerably.
Hi list, I'm sorry if this pile of build errors disturbed you too much. If the error notification is too permissive, I can limit it in two ways: 1) only notify build errors on the first kconfig. There may be a few new error messages show up in the other kconfig builds, however mostly are just irritating duplications. 2) only notify the mailing list directly associated with the git tree. In this particular case, to only CC devel@driverdev.osuosl.org, and to avoid the linux-mtd and linuxppc-dev lists.

Yes, that would be the best thing to do to start with, then let the developers take it from there. thanks, greg k-h

Because I blindly used the lists reported by scripts/get_maintainer.pl ... I'll build a "mailing list <=> git tree" mapping based on MAINTAINERS and use that to build CC list, rather than depending on the source files that the patch randomly touch. > You should put the .config on a web site somewhere and include the URL and > you should not include the whole patch (these were all quite large) - > people can find them given a tree and commit (like above). That's a valid option. Unfortunately I don't have a website to run this for now. Anyway, I'm still on the way improving the kernel testing backend based on your and others' feedback :) > And you sent out 7 reports for the same patch! That's where a website could help. Different kconfigs may trigger different errors for the same commit. So it's a hard decision whether to send emails for all broken kconfigs and risk being a noise, or to limit it to the first broken kconfig and risk lose of information. For now, I can send the patch author all the emails, but CC others only on the first one (with an statement that there are actually more errors in other kconfigs). So that the author that is responsive for fixing the bug get the full information, while the others still can keep track of the error situation. > I approved this bunch, but will not (unless pressured) approve any more. > This scatter gun automated approach is like the boy crying wolf. > I appreciate the effort, but please tone down the reports considerably. Heh, thanks! We should be able to reach a polished automated system that's fast and accurate in the end :-) Thanks, Fengguang
From e2ae715d66bf4becfb85eb84b7150e23cf27df30 Mon Sep 17 00:00:00 2001 From: Kay Sievers <kay@vrfy.org> Date: Fri, 15 Jun 2012 14:07:51 +0200 Subject: [PATCH] kmsg - kmsg_dump() use iterator to receive log buffer content Provide an iterator to receive the log buffer content, and convert all kmsg_dump() users to it. The structured data in the kmsg buffer now contains binary data, which should no longer be copied verbatim to the kmsg_dump() users. The iterator should provide reliable access to the buffer data, and also supports proper log line-aware chunking of data while iterating.
