I use bind mounts, and you can make a squashfs out of 
just /lib/modules/2.6.42.  Still, if somebody other than the original 
developer thinks this might be cool, that's good to know...

Nah, that's not an problem for me.  "There's something wrong with this module" 
is true either way.  Figuring out what is a developer-only issue.

However, you shouldn't have to modify the generic bunzip code when I designed 
the sucker to be able to uncompress into a buffer.  I designed it so 
read_bunzip reads into a destination buffer that the caller provides and 
specifies the length of.  Don't muck up uncompressStream with a callback and 
a wrapper function.
