Subject: [PATCH v2] NFS: SEEK is an NFS v4.2 feature
Date: Wed, 22 Oct 2014 15:53:10 -0400 [thread overview]
Message-ID: <1414007590-14286-1-git-send-email-Anna.Schumaker@Netapp.com> (raw)
Somehow the nfs_v4_1_minor_ops had the NFS_CAP_SEEK flag set, enabling
SEEK over v4.1. This is wrong, and can make servers crash.
