The first optimization is tuning for reiserfs_get_block, I think writepage clustering will be easier (and more beneficial) if we work out the buffer.c changes I've been posting. I also want to change the log block allocation a bit, so the log blocks are allocated as the transaction progresses, instead of all at the end. I think that will make us much more VM friendly, and let me get rid of the inode writing kludges. It'll be a busy weekend ;-) -chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
