It did chain to the original thread; that's how I was able to figure
out the context.  However, it looks like in your reply, you set the
subject to be:

[PATCH] Where we are for this patch?

And the problem is if someone had deleted the original e-mail chain
--- for example, optimizing the kernel stack is not one of the
subjects that I normally closely track, I had already deleted those
e-mail chains.  So all I saw (and I suspect all Al saw) was a message
with the above subject line, and no context.

If you had kept the original subject line, then those of us who mostly
focus on file system stuff would have known that it's an area which is
covered by other maintainers, and we wouldn't have deleted your query
and let someone else respond.

Cheers,

P.S.  I personally find the use "git-send-email" to reply to be so
much of a pain that I just use a non-google.com address to which I can
use a traditional threaded mail-reader (such as mutt) and I can send
e-mail without having to worry about the DMARC nonsense.  :-)
