Subject: Re: [PATCH v2 15/16] Remove local_flags array in struct buffer
Date: Sun, 22 Nov 2020 15:04:06 -0500	[thread overview]
Message-ID: <jwvd005p3bo.fsf-monnier+emacs@gnu.org> (raw)

That's actually the approach I had in mind in my list of "things
I should do at some point" ;-)

I haven't had a chance to look at the actual patches yet, tho.
