Miller" Subject: [patch] zero-bounce block highmem I/O, #13 Message-ID: <20010827123700.B1092@suse.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I've uploaded a new version. Changes since last time includes the following: - Merge BIO_CONTIG from 2.5 bio patches to unify testing of contigious buffer heads (BH_CONTIG in 2.4 tree) (me) - cciss, cpqarray, and ide-dma wrongly used 0 for lastdataend in segment merging, which is wrong since 0 is a valid physical address. A case of s/NULL/0 substition when changing from virtual to physical tests. (davem) - cciss/cpqarray - drop my_sg list, just use the kernel supplied scatterlist. my_sg used unsigned short for length, which is too small. (pointed out by davem, fixed by me) - cciss/cpqarray - rewrite loop-until-empty in request queueing. (me) - BLK_BOUNCE_ANY was b0rken, the ->bounce_page would wrap and thus not work. (pointed davem out by davem, fixed by me -- temporarily, will change to test for highest page instead in next version) - Always use 64-bit type for BLK_BOUNCE_ANY (davem) - IPS must check number of segments mapped by pci_map_sg instead of using the SCSI supplied sg count. (pointed out by davem, fixed by me). IPS still has some highmem fixes pending. 2.4.9 version is here: *.kernel.org/pub/linux/kernel/people/axboe/patches/2.4.9/block-highmem-all-13 2.4.8-ac12 version is here: *.kernel.org/pub/linux/kernel/people/axboe/patches/2.4.8-ac12/block-highmem-all-13-ac12 -- Jens Axboe
