Which ones in particular? Outside of the afs one you looked a below,
the rest should all be of the "need to do IO of some sort" and hence
-EAGAIN is reasonable.

Several of them only do the IO conditionally, which was what I reacted
to in at least cifs.

But I think it's ok to start out doing it unconditionally, and make it
fancier if/when/as people notice or care.

Agree, that was the point I was trying to make in the reply. I'd rather
start simpler and talk to folks about improving it, looping in the
relevant developers for that. I'll leave it as-is for now, modulo the
afs one which was definitely just a mistake.
