=== devfs (Device file system) ===
Dummy, IMFS or new implementation (currently dummy).
There is a minimal implementation based on IMFS. The mount point is fixed to
"/dev". Note that the devfs is only used by the cdev subsystem. cdev has been
adapted so that the full path (including the leading "/dev") is given to devfs.
This saves some copy operations.
devfs_create() first creates the full path and then creates an IMFS generic node
for the device.
TBD: remove empty paths on devfs_destroy().
