locking/atomic, kref: Add kref_read()
...
Since we need to change the implementation, stop exposing internals.
Provide kref_read() to read the current reference count; typically
used for debug messages.
Kills two anti-patterns:
atomic_read(&kref->refcount)
kref->refcount.counter

usnic: add missing clauses to BSD license
...
The usnic_verbs kernel module was clearly marked with the following in
its code:
MODULE_LICENSE("Dual BSD/GPL");
However, we accidentally left a few clauses of the BSD text out of the
license header in all the source files. This commit fixes that: all
the files are properly dual BSD/GPL-licensed. Contributors that might
have been confused by this have been contacted to get their permission
and are Cc:ed here.
