Subject: repack-promisor: extract function to finalize repacking
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dd8c4e12c2da850d67849ccfc221ee1dbf87ce55;p=thirdparty%2Fgit.git

repack-promisor: extract function to finalize repacking

We're about to add a second caller that wants to finalize repacking of
promisor objects. Split out the function which does this to prepare for
that.
