This enforces us to remove duplicated code across the SysFS code. This
results in great simplification of how the SysFS works now, because we
enforce one way to treat SysFSDirectory objects.
This will be used later on to help connecting a node at /sys/dev/block/
that represents a Storage device to a directory in /sys/devices/storage/
with details on that device in that directory.
These methods will be used later on to introduce symbolic links support
in the SysFS, so the kernel will be able to resolve relative paths of
components in filesystem based on using the m_parent_directory pointer
in each SysFSComponent object.
