Hi,

what's the common practice for describing the authors and the copyright of kernel code released under the GPL2?

Let's make an example:

the developer A releases a code.c for the linux kernel and specifies himself and other contributors as Authors.

Some time later the developer B

- refactors the same piece of code (due to massive core changes)
- adds new functionalities
- releases it with the same name/location
- specifies himself as the only Author
- eventually adds a note that this work is based on the work of the initial authors

Is this correct?
How normally behave kernel developers?

Thanx for your help!
