Re: Weirdness of "mount -o remount,rw" with write-protected floppy

But no, this one's clearly a kernel error. If the kernel is giving write errors against the device afterwards, than the kernel's internal state toggled successfully, which is all the mount syscall was trying to do. Mount is just reporting whether or not the syscall succeeded, not whether or not it should have. :)

OK, so there are actually two separate bugs, it seems: one that remounting a RO media in the RW mode succeeds (this "works" for any RO media, as far as I can tell) and the second (this one is specific to the floppy driver only) that a further write to such a falsely rw-remounted media doesn't return (in the user space) an error.
