David, could you provide some feedback please? The patches are stunningly

You bastard! :)
Ok, from a brief look ...
[general]
The code adds an extra indirection over the already existing
file_operations, that IMO already sufficently abstract a file.
The compat code, if I read it correctly, does not support files crossing
32/64 bits boundaries (exec or SCM_RIGHTS).
The compat code is not already finished, I plan to address compat
code on the next version.
How? Compat on sys_read/sys_write?
Yes. More on that later.
[timers]
Returns a structure instead of a 32 bit counter (ala timerfd), and needs
extra compat code.
Yes, but the compat code will be quite small.
Why would that be even justified?
Because the developer may need it.
[signal]
All the discussions that went on for signalfd has been lost. It pins the
task struct and it does not handle process detach signaling.
No, I just went into a different direction.
I'd say wrong, because signalfd addressed valid concerns of quite a few
ppl.
So in this case I may borrow some signalfd code :-) I really like the
signalfd approach, but IMHO the code is quite ugly and duplicates
a lot of hairy code.
