I don't follow -mm myself (since as far as I'm concerned, a lot of the point of -mm is that Andrew takes a lot of load off me). So yes, it was unfair and yes, I'd never have reacted to it in -mm. But I'd really like to get that PG_uptodate bit just fixed - both wrt writeout errors and wrt truncate/holepunch. We had some similar issues wrt ext3 (?) inode buffers, where removing the uptodate bit actually ended up being a mistake.
