Hello, I'd like to attend this years LSF. I've been doing various file system work for the last 6 years, most of that with my head down in btrfs. I'd like to talk about what to do about O_DIRECT. Nobody really owns it and nobody really _wants_ to own it, and we've all been tacking on our own file systems optimizations and work arounds to make the generic stuff work. I'm to the point now where I'm just going to do all the work ourselves inside of btrfs since we need to have different waiting rules. So the question is do we want to just rm -f fs/direct-io.c and let everybody do their own thing, or is there some way we can tease out the actual generic stuff that everybody is going to need to do and adapt everybody to use that? And then theres the question of what are the things we want to do in the generic code, do we want to just do the get pages thing, do we want to still have stuff to build and submit the bios? What about how AIO interacts with it? And best of all can we convince Zach to do all of it for us!
