Either the comment is wrong or something got corrupted.

Tom, Bruce, any idea what could be causing this?  It doesn't really
look fuse related.

I seem to recall something being fixed recently there--I'll try to find
the commit id.

Might have been 2da2c21d7508d34bc6d600df665d84871b65d2b9 "Add a
reference to sunrpc in svc_addsock" ?

Very possibly. That fix went into 2.6.28, and I can confirm that the problem does not reoccur under 2.6.28.2.

Thanks for your help!

David
