Oh.. well, right -- gianfar a bit more comlex in that regard.

At the time of posting it was tested using netconsole only, a few
days later it's was tested using KGDBoE also. So, it works indeed.

Yup, I'm agree here but it's too late. Again. ;-)
This patch already accepted into the -mm (a week or so after the
silence), so.. now I'd rather not bother Andrew with such really
cosmetic changes. But if Jeff would directly apply modfied patch,
I'll send it. ;-)
Anyhow, I'm sincerely appreciate your comments.
