Günther, let me know if everything is OK.

Konstantin, please rebase your work on it. It should mainly conflict 
with changes related to the Landlock ABI version.

Ok, it should be in -next soon. Thanks for your contribution!

Would you like to write a syzkaller test to cover this new access right?
You only need to update the landlock_fs_accesses file with a call to
truncate() returning EACCES and check that it covers
hook_path_truncate(). You can take inspiration from this PR:
https://github.com/google/syzkaller/pull/3133
Please CC me, I can help.

Regards,

This "mode" argument is always 0600. If it's OK with you, I hard code this
mode and push this series to -next with some small cosmetic fixes.

Yes, absolutely. Please do these fixes and push it to -next. :)

Thanks,
