Hi Ross, can you take at my (fully working, but not fully cleaned up) version of the iomap based DAX code here: http://git.infradead.org/users/hch/vfs.git/shortlog/refs/heads/iomap-dax By using iomap we don't even have the size hole problem and totally get out of the reverse-engineer what buffer_heads are trying to tell us business. It also gets rid of the other warts of the DAX path due to pretending to be like direct I/O, so this might be a better way forward also for ext2/4. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
