[PATCH 4.19 201/271] pNFS: Fix a typo in pnfs_update_layout
From: Greg Kroah-Hartman
Date: Thu Jul 25 2019 - 11:02:25 EST
From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
commit 400417b05f3ec0531544ca5f94e64d838d8b8849 upstream.
We're supposed to wait for the outstanding layout count to go to zero,
but that got lost somehow.
Fixes: d03360aaf5cca ("pNFS: Ensure we return the error if someone...")
