Looking up files in sysfs is hard to understand and analyize because we currently allow placing untagged files in tagged directories. In the implementation of that we have two subtly different meanings of NULL. NULL meaning there is no tag on a directory entry and NULL meaning we don't care which namespace the lookup is performed for. This multiple uses of NULL have resulted in subtle bugs (since fixed) in the code. Currently it is only the bonding driver that needs to have an untagged file in a tagged directory. To untagle this mess I am adding support for tagged files to sysfs. Modifying the bonding driver to implement bonding_masters as a tagged file. Registering bonding_masters once for each network namespace. Then I am removing support for untagged entries in tagged sysfs directories. Resulting in code that is much easier to reason about.
