From: Jeff Layton <[email protected]> Currently these mount options aren't accessible via statmount().
The read handler for /proc/#/mountinfo calls security_sb_show_options() to emit the security options after emitting superblock flag options, but before calling sb->s_op->show_options. Have statmount_mnt_opts() call security_sb_show_options() before calling ->show_options.
