Subject: acl option silently ignored?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I came across a debian bug report and confirmed that when you remount
- -o acl, dmesg shows ext4 acknowledging the remount with the acl
option, but /proc/mounts does not show the acl option. Is this a
kernel bug or is it intentional?

The acl mount option is now defaulted on, so it's not a bug that if
you specify the acl option, it won't get displayed in /proc/mounts.
What *is* a bug is that if you specify "mount -o noacl", that doesn't
show up in /proc/mounts.
