From cfbebe59ac6a56c1705388b127c5798197afc205 Mon Sep 17 00:00:00 2001 From: Trond Myklebust <trond.myklebust@fys.uio.no> Date: Fri, 16 Mar 2007 13:38:28 -0800 Subject: [PATCH] nfs: nfs_getattr() can't call nfs_sync_mapping_range() for non-regular files Looks like we need a check in nfs_getattr() for a regular file. It makes no sense to call nfs_sync_mapping_range() on anything else. I think that should fix your problem: it will stop the NFS client from interfering with dirty pages on that inode's mapping.
