Message-Id: <1222717460.30627.56.camel@think.oraclecorp.com> Date: Mon, 29 Sep 2008 15:44:20 -0400 From: Chris Mason <chris.mason@...cle.com> To: linux-fsdevel <linux-fsdevel@...r.kernel.org>, linux-kernel <linux-kernel@...r.kernel.org>, Andrew Morton <akpm@...ux-foundation.org> Subject: [RFC] Btrfs mainline plans Hello everyone, Thanks to help from David Woodhouse and Linus, I have btrfs source repos migrated over to git. My goal is to make the sources easier for people to review, and to start some discussions around the best time to merge Btrfs. The current code has a number of problems (and this is not a complete list): * The disk format is not finalized * ENOSPC can result in BUG() * blocksize != pagesize does not work * Error handling is missing in a number of places But, the code is very actively developed, and I believe the best way to develop Btrfs from here is to get it into the mainline kernel (with a large warning label about the disk format) and attract more extensive review of both the disk format and underlying code. The Btrfs developers are committed to making the FS work and to working well within the kernel community. I think everyone will be happier with the final result if I am able to attract eyeballs as early as possible. The plan is to have the disk format finalized by the end of the year. I do expect to have a provisional disk format over the next 2 weeks that should have all the moving pieces btrfs needs to implement the remaining 1.0 features, and I hope to restrict any additional format changes after that to include backward compatibility.
