A better way to do F_SEAL_FUTURE_WRITE seal was discussed [1] last week
where we don't need to modify core VFS structures to get the same
behavior of the seal. This solves several side-effects pointed out by
Andy [2].

Suggested-by: Andy Lutomirski <luto@kernel.org>
Fixes: 5e653c2923fd ("mm: Add an F_SEAL_FUTURE_WRITE seal to memfd")  

What tree is that commit in?  Can we not just fold this in?  

It is in linux-next. Could we keep both commits so we have the history?

Well, its in Andrew's mmotm, so its up to him.

Unless mmotm is more magical than I think, the commit hash in your fixed
tag is already nonsense. mmotm gets rebased all the time, and is only
barely a git tree.

I wouldn't go so far to call it nonsense. It was a working patch, it just did
things differently. Your help with improving the patch is much appreciated.

I’m not saying the patch is nonsense — I’m saying the *hash* may be nonsense. akpm uses a bunch of .patch files and all kinds of crazy scripts, and the mmotm.git tree is not stable at all.

I am Ok with whatever Andrew wants to do, if it is better to squash it with
the original, then I can do that and send another patch.

From experience, Andrew will food in fixups on request :)
