Subject: [PATCH 1/5] NFS: Memory allocation failures are not server fatal errors
Date: Sat, 14 May 2022 10:08:10 -0400 [thread overview]
Message-ID: <20220514140814.3655-1-trondmy@kernel.org> (raw)
From: Trond Myklebust <trond.myklebust@hammerspace.com>
We need to filter out ENOMEM in nfs_error_is_fatal_on_server(), because
running out of memory on our client is not a server error.
Reported-by: Olga Kornievskaia <aglo@umich.edu>
Fixes: 2dc23afffbca ("NFS: ENOMEM should also be a fatal error.")
Cc: stable@vger.kernel.org
