Yes, I know this. In fact this thread started with the pull request you sent 
to Linus on Feb 23. My patches to fs/sysv already credited you with the 
"Suggested-by:" tag.

Sorry if I have not been clear about what I was talking about.

My series of patches for fs/ufs (again all with the "Suggested-by: Al Viro 
<...>" tags - it's only missing in the cover letter) are at the following 
address since Dec 29, 2022. I don't know why they haven't yet applied to the 
relevant tree:

https://lore.kernel.org/lkml/20221229225100.22141-1-fmdefrancesco@xxxxxxxxx/

As far as fs/minix is regarded I submitted nothing for it. I'm not sure about 
who wants to work on the patches for that filesystem.

I know nothing about how fs/minix is designed and I don't yet know whether or 
not I can easily model the patches to it after sysv and ufs series. I'll take 
a look in the next days.

Sorry for the confusion about ext2. I think I have not been clear about my 
intentions. Please let me summarize:

1) You sent the pull request for sysv. In that email to Linus you wrote 
"Fabio's "switch to kmap_local_page()" patchset (originally after the
ext2 counterpart, with a lot of cleaning up done to it; as the matter of
fact, ext2 side is in need of similar cleanups - calling conventions there
are bloody awful).  Plus the equivalents of minix stuff..."

2) I replied by asking whether someone else were already working on ext2 as 
you suggested above. I asked for that information because I thought I could do 
the work modeling after sysv and ufs.

3) You wrote about a "demo patchset" somewhere in one of your trees.

4) Jan replied that he likes your "demo patchset" (I haven't yet taken a look 
at those because I supposed they were modeled after the suggestions you 
provided to me for sysv and ufs, so I thought I have no reasons to take a look 
at them) and asked me to "pick your demo patches and put them to completion".

Now I'm confused about what you want to be done with your "demo patchset" 
because I don't know what you mean by "demo" and why you showed you have that 
patchset.

I mean... do you want them only tested and reviewed? Any other task to be done 
on them?

Thanks,

Fabio
