Call me dumb, but why would someone use "eject" on a non-physically ejectable device such as a memory stick ? I use it on CDs, I've used it on Sun floppy drives, but USB memory stick ??? After the umount, I just have to pull it from the plug and that's all. I don't catch what an eject command can bring me on top of that :-/ Willy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
