Subject: [PATCH 3/3] NFSv4.2: Change the default KConfig value for READ_PLUS
Date: Wed, 30 Nov 2022 13:15:27 -0500 [thread overview]
Message-ID: <20221130181527.766485-3-anna@kernel.org> (raw)
In-Reply-To: <20221130181527.766485-1-anna@kernel.org>
From: Anna Schumaker <Anna.Schumaker@Netapp.com>
Now that we've worked out performance issues and have a server patch
addressing the failed xfstests, we can safely enable this feature by
default.

- This is intended for developers only. The READ_PLUS operation has

- be used in production.
+ Choose Y here to enable the use of READ_PLUS over NFS v4.2. READ_PLUS
