Ok, fair enough. 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.
