This is required to provide uuid based integrity functionality for:
ima_policy (fsuuid option) and the 'evmctl' command ('--uuid' option).

I took this patch, thanks a lot for this but I have changed the sob-chain to:
Co-developed-by: Oleksij Rempel <o.rempel@pengutronix.de>
Co-developed-by: Juergen Borleis <jbe@pengutronix.de>
Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>
Namely, "patch was created by Steffen Trumtrar, Oleksij Rempel and
Juergen Borleis.
Steffen Trumtrar committed it and Juergen Borleis later sent it to the
mailing list".
Is this right?

Andy,

Hmm, I didn't know that helper.
The only user in fs/ seems to be zonefs, all other filesystems do a plain memcpy().
Do you want me do a patch that converts all users in fs/ to import_uuid()?
Thanks,

Okay. I've dropped the patch from linux-next.
Juergen, please address Andy's comments and resend.
