Re: [PATCH] /dev/epoll update ...

One more question: if I guess wrong initially about how many
file descriptors I'll be monitoring with /dev/epoll, and I need
to increase the size of the area inside /dev/epoll in the middle of
my scan through the results, what is the proper sequence of calls?

Some possibilities:

1) EP_ALLOC, and continue scanning through the results

2) EP_FREE, EP_ALLOC, EP_POLL because old results are now invalid

3) EP_FREE, EP_ALLOC, write new copies of all the old fds to /dev/epoll,
    EP_POLL, and start new scan

I bet it's #3. Am I right?
