Hi Evgeniy,

I think the point is this.  You want to introduce a change that
address the needs of a single application.  Many others see the
change, which though it may be simple and quick to implement, as "an
ugly hack" -- it messes up an otherwise rather well designed API.
Should we make such a change?  I think not -- and others are echoing
that sentiment.  Your argument that "we should do this because no-one
else has proposed a better way" is not sufficient rationale for
uglifying this API to serve the needs of a single app -- the argument
will not fly, no matter how many times you repeat it.  (Your statement
"Critics without suggestions is useless" does not hold: one very
useful purpose of critics is to maintain the status quo of "good
taste" in API design.)

At this stage, I see three possibilities -- you maintain an
out-of-mainline patch for the kernel, and distribute that with your
app; you work out some other *userspace* solution to your problem; or
someone comes up with inotify-ng, designed to address your needs and
those of others (okay, we may not know what those other needs are yet,
but the question is if we could come up with an inotify-ng design that
can extensible in a sane way).  I know that none of these options will
be what you are happy with, but all of them have more life than your
proposal, IMO.

Cheers,

Michael
