Marco Casaroli 58e227a8a5 Documentation: Document dlopen() reference counting. ...

Describe the shared library open semantics in the FLAT and PROTECTED
builds: dlopen() of a library that is already loaded returns a handle
to it and takes an additional reference, and the library is unloaded
only when the last handle is closed.  Note the consequences that follow
from having a single instance: libraries are matched by basename, data
is shared by all users, and constructors and destructors run once.

Contrast this with insmod(), which still rejects a duplicate module
name, and note that dlopen() is not implemented in the KERNEL build.
