hi Doug,
 thanks for the report and for bisecting!

I think this bug has been fixed, but the fix hasn't landed upstream yet.
If you
   git pull git://git.linux-nfs.org/~bfields/linux.git nfs-next

you should get

Commit 3c86794ac0e6 ("nfsd/nfsd3_proc_readdir: fix buffer count and page pointers")

which should fix this.


Bruce:  I don't see that patch in your "for-5.1" branch, but you said
   "Queuing up for 5.1."
Did something go awry?

Thanks,
NeilBrown
