From 8850df999cd16aa141098e2e8be04a590276f3cc Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 28 Sep 2007 17:20:07 -0400 Subject: NFS: Fix atime revalidation in read() NFSv3 will correctly update atime on a read() call, so there is no need to set the NFS_INO_INVALID_ATIME flag unless the call to nfs_refresh_inode() fails.
