From e1552e199857109d4b25b9163eff4646726eee3d Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 14 Apr 2007 19:07:28 -0400 Subject: [PATCH] NFS: Fix an Oops in nfs_setattr() It looks like nfs_setattr() and nfs_rename() also need to test whether the target is a regular file before calling nfs_wb_all()...
