Patch(es) committing - (stupid) question

[Aleš Nesrsta]

Hi,

I have stupid question related to organization of committing of patches 
- I am currently little bit confused.

Vladimir wrote to me in some latest e-mail :
"I don't see any messages in my mailbox from you tagged as pending
patches."

And, additionally, I see only Vladimir's commits in trunk ChangeLog in 
the last time.

I.e. it looks for me like something changed here in the meantime and I 
missed it - maybe only Vladimir can commit patch(es) and I should ask 
him in some (for me currently unknown) way - ?

So, my question is:
How should I correctly ask commit of my patch(es) into trunk?

(Question is not related to BZR procedure, only to development 
organization - how to ask commit of patch or how to get permission to do 
commit myself, if it is still possible.)

Sorry if it is written somewhere on GRUB web-pages - but for the first 
look I don't see any related information how the GRUB development is 
organized.

BR,
Ales
