This was my first trial, but I could not get it working. I would have to change code in VFS. But:
/* * Alters the mount flags of a mounted file system. Only the mount point * is used as a reference - file system type and the device are ignored. * FS-specific mount options can't be altered by remounting. */
static int do_remount_sb(struct super_block *sb, int flags, char *data)
Seems to be a bad idea to change mount options this way? So I left my hands off.
