I don't know if this JIT can avoid GPL licence? Since the filter sits on the userspace application, but finnally it is compiled and linked into kernel to execute. any idea on this? or it is a grey area, no one specify this?
From my point of view, this will not volidate the GPL licence. Linus can give some hint on this?
Also there is a trend, more and more code can be developed on userspace, such as UIO framework, it makes driver can be implemented in the userspace, this will avoid GPL licence issue. Then later on, more and more persons develop non-GPL licenced code, right?
