Subject: [PATCH RFC 04/15] SUNRPC: Fail faster on bad verifier
Date: Mon, 18 Apr 2022 12:51:34 -0400	[thread overview]
Message-ID: <165030069404.5246.6833136485402480106.stgit@oracle-102.nfsv4.dev> (raw)
In-Reply-To: <165030062272.5246.16956092606399079004.stgit@oracle-102.nfsv4.dev>

A bad verifier is not a garbage argument, it's an authentication
failure. Retrying it doesn't make the problem go away, and delays
upper layer recovery steps.
