From 7c61f0d3897eeeff6f3294adb9f910ddefa8035a Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Tue, 14 Apr 2015 10:34:20 -0400 Subject: [PATCH] NFS: Add a stub for GETDEVICELIST d4b18c3e (pnfs: remove GETDEVICELIST implementation) removed the GETDEVICELIST operation from the NFS client, but left a "hole" in the nfs4_procedures array. This caused /proc/self/mountstats to report an operation named "51" where GETDEVICELIST used to be. This patch adds a stub to fix mountstats.
