Is /dev/epoll scheduled for official inclusion anytime soon?

Hello all.

I've been playing around with Davide Libenzi's "/dev/epoll" patch and have
been very impressed by the performance figures (see his paper at for some
numbers) - it seems to exhibit really excellent scaling.

Given the sheer utility of using /dev/epoll in a largescale server, are
there any plans to roll it into the mainline kernel at any point? If not,
why / is there an equivalent scheduled for inclusion?

Clearly, IMHO, Linux needs something that can scale as well as BSD's kqueue
and Solaris's /dev/poll. /dev/epoll seems to be an excellent answer.

rather robust read/write support of NT filesystems!
