Oh, I see.

It's still a bit strange, isn't it?  The "inotify" identifier doesn't
have the colon.  I guess it's unavoidable, as this multiple-name-value
line is being mixed into the same pseudo-file as single name-value lines.

Where *is* this pseudo-file, anyway?  The changelog doesn't tell us
where it lies in the filesystem.

I know!  I'll search the documentation!  /proc/sys/fs/epoll/..., yes?

btw, Documentation/sysctl/fs.txt is missing documentation for
max_user_instances and max_queued_events.  Perhaps you can fix that
when providing the documentation changes for your patch :)
