fs: prepend statmount.mnt_opts string with security_sb_mnt_opts()

Browse source

commit 056d33137b upstream.

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.
