mount options: add generic_show_options()
Add a new s_options field to struct super_block. Filesystems can save mount options passed to them in mount or remount. It is automatically freed when the superblock is destroyed. A new helper function, generic_show_options() is introduced, which uses this field to display the mount options in /proc/mounts. Another helper function, save_mount_options() may be used by filesystems to save the options in the super block.
