From 1e8968c5b0582392d5f132422f581e3ebc24e627 Mon Sep 17 00:00:00 2001 From: Niels de Vos Date: Tue, 17 Dec 2013 18:20:16 +0100 Subject: [PATCH] NFS: dprintk() should not print negative fileids and inode numbers A fileid in NFS is a uint64. There are some occurrences where dprintk() outputs a signed fileid. This leads to confusion and more difficult to read debugging (negative fileids matching positive inode numbers).
