I don't know where you read that, but:
1. There is no "kernel support" option
2. Assuming you mean "kernel oplocks", the man page specifically says "
You should never need to touch this parameter."

According to the man page, IRIX and linux 2.4 (and presumably greater)

It sounds like it relies on a generic change notification system rather
than something that is specificly designed for oplocks, probably Inotify
or maybe just dnotify.
From the kernel's menuconfig help on inotify: "If unsure, say Y". If
you are compiling your own kernel you should only remove things that you
*know* you wont need. Stick with the recommended or existing settings
everywhere else and you don't have anything to worry about.
