it wasn't that many. For some obvious reasons I only tested the RHEL and
Fedora kernels and vanilla plus stable series.

I haven't checked within the code, but the manual page exports(5) states
subtree checking as being on by default. And it doesn't mention any
difference to 2.4 kernels.
What is the reason behind your question? Does disabling subtree checking
changes something?
