From 7cb9cd9aa2eafe869935d4168031f1ed376d924c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 17 Jul 2017 10:11:11 -0400 Subject: [PATCH] NFS: Fix a reference and lock leak in nfs_lock_and_join_requests() Yes, this is a situation that should never happen (hence the WARN_ON) but we should still ensure that we free up the locks and references to the faulty pages.
