I think we're getting on a very slipper slope if we think about application here. Buffered I/O application must deal with torn writes at any granulairty anyway, e.g. fsync + rename is the only thing they can rely on right now (I actually have software O_ATOMIC code to avoid this, but that's another story). Direct I/O using application can make assumption if they know the sector size, and we must have a way for them to be able to see our new "subsector sector size". And thos application are few inbetween but also important so needing special cases for them is fine. Although those are the most likely ones to take advantage of byte addressing anyway. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in
