any way to re-release git's block sha1 implementation under a different license?

Hi,

I am reaching out because in my personal project (
https://github.com/liuliu/ccv
), I used the block sha1 implementation (
https://github.com/git/git/blob/master/block-sha1/sha1.c) in git. It is a
fast, generalized and standalone implementation, however, since it is a
part of git, it is under GPL license. Is there any possibilities for the
original author/authors to release this particular piece of code under BSD
/ MIT or Apache license? Thanks!
