This was hidden away inside the create_ok() function. In the case that there was an existing inode, and a lookup can be substituted for a create (which is the case with regular files when the O_EXCL flag is not in use) then we were doing a second lookup in order to return the inode. This patch merges these two lookups into one. This can be done by passing a flag to gfs2_dir_search() to tell it to just return -EEXIST in the cases where we don't actually want to look up the inode.
