From: Andrew Morton on 1 Jun 2006 04:50 ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc5/2.6.17-rc5-mm2/ - A cfq bug was fixed in mainline, so the git-cfq tree has been restored. - Various lock-validator and genirq fixes have been added. Should be slightly less oopsy than 2.6.17-rc5-mm1. - I just realised that I've been accidentally not updating the PCI tree for a while. Will be restored in next -mm. - Has been booted and has passed various stress-tests on quad x86_64, quad ancient-Xeon, quad power4, quad ia64, dual old-PIII and a modern pentium-M laptop. So if it breaks, it's your fault. Boilerplate: - See the `hot-fixes' directory for any important updates to this patchset. - To fetch an -mm tree using git, use (for example) git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1 - -mm kernel commit activity can be reviewed by subscribing to the mm-commits mailing list. echo "subscribe mm-commits" | mail majordomo(a)vger.kernel.org - If you hit a bug in -mm and it is not obvious which patch caused it, it is most valuable if you can perform a bisection search to identify which patch introduced the bug. Instructions for this process are at http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt But beware that this process takes some time (around ten rebuilds and reboots), so consider reporting the bug first and if we cannot immediately identify the faulty patch, then perform the bisection search. - When reporting bugs, please try to Cc: the relevant maintainer and mailing list on any email.

I put the fix for slab corruption into mm1, and it did indeed cure that. However, if I add git-cfq.patch, my box still explodes. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Andrew, you probably want to leave out git-cfq for a few days as it'll throw rejects once Linus pulls the for-2.6.17 cfq urgent fixes. I'll fixup the branch and the apparently silly bug that crept in that branch and give you a ping about when to reenable it! -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
