This is not based on my attempt to make the xfs writeout path generic.
Alex's variant is a lot simpler and thus missed various bits required
for high sustained writeout performance or xfs functionality.

I'd very appreciate any details about high writeout performance.

That doesn't mean I want to arge against Alex's code although I'd of
course be more happy if we could actually shared code between multiple
filesystems.

I'm not against at all, of course. but xfs writeout code looks .. hmm ..
very xfs :)

thanks, Alex
