GFS2 has been passing i_mode within NFS File Handle. Other than the wrong assumption that there is always room for this extra 16 bit value, the current gfs2_get_dentry doesn't really need the i_mode to work correctly. Note that GFS2 NFS code does go thru the same lookup code path as direct file access route (where the mode is obtained from name lookup) but gfs2_get_dentry() is coded for different purpose. It is not used during lookup time. It is part of the file access procedure call. When the call is invoked, if on-disk inode is not in-memory, it has to be read-in. This makes i_mode passing a useless overhead. Signed-off-by: S. Wendy Cheng <wcheng@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
