I'm attending a SNIA meeting today to discuss a (cross-OS) data integrity aware API. We'll see what comes out of that. With the Linux hat on I'm still mainly interested in pursuing the sys_dio interface Joel and I proposed last year. We have good experience with that I/O model and it suits applications that want to interact with the protection information well. libaio is also on my list. But obviously any help and input is appreciated... -- Martin K.
