system update question

["Andrey N. Oktyabrski" <ano@xxxxxxxxx>]

Good day.

I installed the 2.10.1 release. Then I want update it to "stable" 
branch, for example, once per week. What parameters I must use with
make src-create/src-update ?
Are these parameters described anywhere (in howto)? Where I can read 
about system updating?

By default /usr/src checkout use "master" - it is not what I want.
