(fwd) Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org To: linux-mm List-ID: Hi guys, I just got this message from Hans Reiser (the main ReiserFS coordinator), who says that ReiserFS will be 40-bits (1TB filesize) ready by june/juli this year. Now we (the MM guys) need to get together and make the MM layer 40-bit transparent too (or 41-bit). Any takers? Rik. ---------- Forwarded message ---------- Date: Wed, 22 Apr 1998 00:53:03 -0700 From: Hans Reiser To: H.H.vanRiel@phys.uu.nl Cc: reiserfs Subject: (reiserfs) Re: Maybe we can do 40 bits in June/July. Hi Rik, Ok, I propose the following. After we stabilize reiserfs but before we ship it to users we will send you an email saying we are ready to move to 40 bits. Then, working in parallel, we will convert both mm and reiserfs to 40 bits. You (or somebody you name) will coordinate the mm portion, and I (or Vladimir) will coordinate the reiserfs portion. I anticipate that we will be able to convert ~June, not later than July. I anticipate that it will be easy for reiserfs to convert, and take not long to debug any reiserfs problems that occur. Since changing mm will inconvenience other things besides reiserfs, I imagine that you will want it to be deferred until reiserfs is stable enough for users to benefit from using 40 bit reiserfs. Maybe we can implement 40 bits as a #define in the reiserfs code. Incidentally, I prefer 40 bits for reiserfs for yet another reason: 64 bits would make our keys overly large. I am sure that there are a lot of details which we can work out in June. Does this plan sound good to you?
