It makes it easier (at least for me) to see that those are all related to each other (in your case, sematich patches). In order to do that with git you could: $ git format-patch -o patches --cover-letter linus/master [ edit cover letter] $ git send-email --to lkml patches/ that will do the trick. Thanks -- balbi
