This typically indicates that you should send four patches
instead of one.
How can we create samples / please provide samples.

Was this completely missing so far or what is the
reason for this change?

You cannot use a static variable, add it to the context instead.

Use "&" instead of "%".

This line does not make sense...
Please split your patch and resend, Carl Eugen
