Message-Id: <11774025432481-git-send-email-jens.axboe@oracle.com> Date: Tue, 24 Apr 2007 10:15:28 +0200 From: Jens Axboe <jens.axboe@...cle.com> To: linux-kernel@...r.kernel.org Subject: [PATCH 0/15] CFQ IO scheduler patch series Hi, I have a series of patches for the CFQ IO scheduler that I'd like to get some more testing on. The patch series is also scheduled to enter the next -mm, but if I'd like people to consciously give it a spin on its own as well. The patches are also available from the 'cfq' branch of the block layer tree: git://git.kernel.dk/data/git/linux-2.6-block.git and I've uploaded a rolled up version here as well: http://brick.kernel.dk/snaps/cfq-update-20070424 The patch series is essentially a series of cleanups and smaller optimizations, but there's also a larger change in there (patches 4 to 7) that completely rework how CFQ selects which queue to process. It's an experimental approach similar to the CFS CPU scheduler, in which management lists are converted to a single rbtree instead. So give it a spin if you have the time, and let me know how it performs and/or feels for you workload and hardware. cfq-iosched.c | 676 ++++++++++++++++++++++++++------------------------ 1 file changed, 357 insertions(+), 319 deletions(-) -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
