From 1775bc342c6eacd6304493cbb2e0cda1a0182246 Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Fri, 20 May 2011 13:47:33 +0200 Subject: NFSv4.1: purge deviceid cache on nfs_free_client Use the pnfs_layoutdriver_type both as a qualifier for the deviceid, distinguishing deviceid from different layout types on the server, and for freeing the layout-driver allocated structure containing the nfs4_deviceid_node.
