--- Comment #2 from Theodore Tso <tytso@....edu> ---
Please note that Nick Krause was banned from the Linux Kernel list because he
has a tendency to guess, and while it was one thing to be wasting kernel
developers' time, it was quite another when he was giving bad advice to users
who were looking for help.

Having looked at the warning issued on line fs/dcache:1318, which is due to a
dentry in the file system to be unmounted was still being used.  The
nfs_put_client() call has nothing to do with dentries.

If you want to try Nick's suggestion, please feel free.  But it's not likely to
fix things, and it might make things worse.
