Subject: [PATCH] ceph: Fix an Oops in error handling
Date: Tue, 2 Feb 2021 08:47:39 +0300	[thread overview]
Message-ID: <YBjne8A1gn0mvQtT@mwanda> (raw)

The "req" pointer is an error pointer and not NULL so this check needs
to be fixed.

Fixes: 1cf7fdf52d5a ("ceph: convert readpage to fscache read helper")
