Re: Removing Mandatory Locks

I thought the main user was Samba and/or otherwise providing file service for M$ systems?

I'm all for ripping it out too. It's an insane interface anyway.

I've not heard a single complaint about this being turned off in
fedora/rhel or any other distro that has this disabled.

I'd love to remove it, we could absolutely test it. The fact that
several major distros have it disabled makes me think it's fine.

FWIW, it is now disabled in Ubuntu too:

But as always, it would be good to check Android.

It looks like it's enabled (checking the Pixel 4 kernel image), but it's
not specifically mentioned in any of the build configs that are used to
construct the image, so I think this is just catching the "default y". I
expect it'd be fine to turn this off.

I will ask around to see if it's actually used.
