Sorry for the late reply. Why do we need a different license to GPLV2
sources that  contributors submitted.?  As Mathieu mentioned, I think
that  GPLV2 based some sources needs  to be relicense  to  trace
non-GPL applications
for some developers and some companies.

In real, Some open source  like QT, MySQL is licensed using dual
license for business strategy. tracepoint.c/marker.c file is GPLv2
currently.

Can  we re-distribute with dual license (e.g: bsd/gplv2 or lgpl
2.1/gplv2)   about some source of linux kernel source? I think that
linux kernel source is GPLv2 only. Frankly speaking, I am not know
exactly about  legal issues of your questions.

Thanks,
