git clone of linux kernel provides only compressed pack files

[Manavendra Nath Manav]

Hi All,

I cloned 3.2 kernel from git repository, but I am not seeing any
source files. The .git directory contains .git/objects/pack/*.pack
file which is huge and it seems all source code with commit revision
is stored there. When I do "git unpack-objects -r < xyz.pack", it
completes 100% but still no source files show up. The only thing it
generates is some more entries in .git/objects/ directory. The same
problem also occurs when I try to clone android repository. Pls help,
I am sure I am missing some obvious step here.

>From the man page of git-unpack-objects: "Objects that already exist
in the repository will not be unpacked from the pack-file. Therefore,
nothing will be unpacked if you use this command on a pack-file that
exists within the target repository." I guess this is the problem I am
facing. How do I extract the linux souce files (HEAD branch) from pack
file?
