I sorry for the delay in my answer, but I needed to set up a minimal
tutorial to show what I am working on and why I need a feature like the
one I am proposing.
Please, have a look of the README.md page here:
(everything can be downloaded and tested)
Is that similar to what user-mode linux does? I mean the principle.
I am not trying to port some tools to use user-space implemented
stacks or device
drivers/emulators, I am seeking to a general purpose approach.
You still intersect *each* syscall, why not to do the same for
and replace events with correct value? Seems you do something similar
in a vu_wrap_poll.c: wo_epoll_wait(), right?
Don't get me wrong, I really want to understand whether everything
looks so bad without proposed change. It seems not, because the whole
is based on intersection of each syscall, thus one more one less - it
become more clean and especially does not look like a generic purpose
which you seek. I may be wrong.
