[RFC] [PATCH 0/4]Multiple block allocation and delayed allocation for ext3
Hi All, Here are the updated patches to support multiple block allocation and delayed allocation for ext3 done by me, Badari and Suparna. [PATCH 1/4] -- multiple block allocation for current ext3. (ext3_get_blocks()). [PATCH 2/4] -- adding delayed allocation for writeback mode [PATCH 3/4] -- generic support for cluster pages together in mapge_writepages() to make use of getblocks() [PATCH 4/4] -- support multiple block allocation for ext3 writeback mode through writepages(). Have done initial testing on dbench and tiobench on a 2.6.11 version of this patch set. Dbench 8 thread throughput result is increased by 20% with this patch set. dbench comparison: (ext3-dm represents ext3+thispatchset) http://www.sudhaa.com/~ram/ols2005presentation/dbench.jpg tiobench comparison: http://www.sudhaa.com/~ram/ols2005presentation/tio_seq_write.jpg Todo: - bmap() support for delayed allocation - page reserve flag to indicate the delayed allocation - ordered mode support for delayed allocation - "bh" support to enable blocksize = 1k/2k filesystems Cheers, Mingming - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
