All the patches have been posted to linux-kernel before, and various comments (and acks) have been taken into account. (see http://thread.gmane.org/gmane.linux.kernel/609943) It's a fairly nice performance improvement, so would be good to get in. It's survived a few hours of *mumble* high-stress database benchmark, so I have high confidence in its stability. The following changes since commit 21511abd0a248a3f225d3b611cfabb93124605a7: Linus Torvalds (1): Merge branch 'release' of git://git.kernel.org/.../aegl/linux-2.6 are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/willy/misc.git dmapool Matthew Wilcox (7): Move dmapool.c to mm/ directory dmapool: Fix style problems Avoid taking waitqueue lock in dmapool dmapool: Validate parameters to dma_pool_create dmapool: Tidy up includes and add comments Change dmapool free block management pool: Improve memory usage for devices which can't cross boundaries drivers/base/Makefile | 2 +- drivers/base/dmapool.c | 481 ---------------------------------------------- mm/Makefile | 1 + mm/dmapool.c | 500 ++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 502 insertions(+), 482 deletions(-) delete mode 100644 drivers/base/dmapool.c create mode 100644 mm/dmapool.c -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
