Did you (re)packed this repository, running "git gc", or "git repack"?
Currently git either downloads small packs, or loose objects; it needs
to repack to make repository size smaller.

BTW. the largest git repository is 1.6G OpenOffice.org conversion,
with > 2G checkout, and some large binary files under version
control. Mozilla and GCC, other large repos, got under 0.5G IIRC.
So kernel should be quite smaller.

There is so called "shallow clone" feature, which allows to clone only
part of history. Currently it dupports only --depth, i.e. number of
commits from tips; it could I guess support providing tag as
delimiter. (You are welcome to implement it ;-).
