Noam, All,

I don't think Thomas provided a SoB line so far. You can't add such a
line for someone else, unless they explicitly stated so. A SoB-line is
binding:

Your patch is space-mangled: the leading tabs have been replaced with
spaces. Can you try to use 'git send-email' to send the mails? This is
known to work correctly most of the case, whereas some user-friendly
mailers (lie the ones from MS) have issues properly sending patches.

Superfluous empty line.

Add something like:

    Leaving this empty will also use the default "buildroot" value.

Otherwise, looks good.
