Ok, the updated tree is here: http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/new-dio This moves your O_SYNC patch earlier and makes it not directly assign bi_opf. Then comes the main direct I/O path with the various folds, and a use after free fix ported from the iomap code in the completion handler. Last comes the I/O completion handler split - I don't think it's worth it, but if you prefer it that way go ahead and fold it in. I couldn't do the bio_kmalloc conversion as bio_kmalloc seems to not like the front pad. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
