Now that /sys/class/net/bonding_masters is implemented as a tagged sysfs file we can remove support for untagged files in tagged directories. This change removes any ambiguity of what a NULL namespace value means. A NULL namespace parameter after this patch means that we are talking about an untagged sysfs dirent. This makes the sysfs code much less prone to mistakes when during maintenance. Signed-off-by: Eric W.
