Subject: [PATCH AUTOSEL 5.5 368/542] NFS: Fix fix of show_nfs_errors
Date: Fri, 14 Feb 2020 10:46:00 -0500
Message-ID: <20200214154854.6746-368-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>

From: Trond Myklebust <trondmy@gmail.com>

[ Upstream commit 118b6292195cfb86a9f43cb65610fc6d980c65f4 ]

Casting a negative value to an unsigned long is not the same as
converting it to its absolute value.

Fixes: 96650e2effa2 ("NFS: Fix show_nfs_errors macros again")
