[PATCH 0/2] staging: most: prevent module removal if configfs directory is populated

[Christian Gromm]

Currently the core module does not hold any reference to component modules.
Hence, a component could be unloaded from the system anytime. Even if the
configuration interface is still being populated with configfs
items/groups.
User space then has no chance to fix the usage count by calling rmdir on
such a config item/group, as the respective directory does not exist
anymore. In this situation the core module cannot be unloaded anymore.
This patch set fixes this issue by holding a reference as long as the
configfs items exist.
