From 1ca277d88dafdbc3c5a69d32590e7184b9af6371 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 11 Mar 2009 14:10:25 -0400 Subject: [PATCH] NFS: Shrink the struct nfs_fattr We don't need the bitmap[] field anymore, since the 'valid' field tells us all we need to know about which attributes were filled in... Also move the pre-op attributes in order to improve the structure packing.
