PATCH 1/1 exports: document change to "insecure" export option
From: "J. Bruce Fields" <[email protected]>
We're changing the kernel to allow gss requests from high ports even when "secure" is set.
If the change gets backported to distro kernels, the kernel version may be an imperfect predictor of the behavior, but I think it's the best we can do.
