Linus,
I posted the attached one-line patch several weeks ago and have been
running it without incident. I'd like to see it make it into 2.2.
Basically, the NetworkAppliance .snapshot patch that went in somewhere
around 2.1.130 only worked (for me at least) when the .snapshot
directory was accessed from the mount point. Accessing .snapshot
directories further down in the directory caused NFS I/O errors.
My patch gets rid of the condition IS_ROOT(...) and the errors go away.
This patch is relative to 2.2.0-pre4-ac1 (or just pre4).

PS: Sorry, but I forgot the patch last time.
