Hi -
- Can we have linux stable point release content in tilt-3.4?
Rather than my doing it, isn't it better to add it to llc-3.4 and merge it on the lt history tree periodically? That way every lt can get them from one place.
I don't see why merging the stable release contents would be an issue. We could keep updating the tree based on stable-only releases, as long as we still have at least one Landing Team interested on consuming it.
This would be another job that would probably be automated by Andrey's scripts.
Right it should usually be simple, although don't forget there is quite a lot of avant garde content in llct, such as Androidization. Just today I saw Xavier at TI find that merging of stable had a patch conflicting with llct Androidization content.
So, it turns out that is a good example.
I researched the conflict and found a thread from RMK rejecting the patch 96714b5dfe283cd8ab13aac1f9ccb565064af152 that seems to have come in by Androidization series via llct.
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/014116.html
We decided to take the kernel.org stable version of the patch 6019ae78aa65afe273da8c0dfeed8e89fb5edf8f which removes some locking evil in the Androidization version, which RMK noted opened up a horrible race.
Xavier then found a ghastly bug that had previously been impossible to track down disappeared.
So we now know that 96714b5dfe283cd8ab13aac1f9ccb565064af152 we had been happily pushing out on everyone in llct-3.4 is a terrible idea, not just for TILT but any kernel that has it in will suffer from very hard to reproduce mm instability under stress, and needs reverting in favour of the version that went in kernel.org stable.
But now we know about that flaw in llct-3.4 should we not do something about it?
Yeah, at least for stable related changes I believe it'd make a lot of sense to push those to llct-3.4.
Andrey, let's also coordinate the stable updates for llct-3.4 during this cycle, and then review the issues, if we get any, after the first merge/update.
Cheers,
I've created the linux-linaro-core-3.4 branch: http://git.linaro.org/gitweb?p=kernel/linux-linaro-tracking.git%3Ba=shortlog... (and the manifest: http://git.linaro.org/gitweb?p=kernel/linux-linaro-manifest.git%3Ba=shortlog...)
At the moment this is just something to start from: the old known llct_3.4 with the updated Gator. The rest should follow soon.
Thanks, Andrey
