Subject: treewide: enumerate promisor objects via `odb_for_each_object()`
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=98f6927c6052b73a70d80780e17c86dc73c149a7;p=thirdparty%2Fgit.git

treewide: enumerate promisor objects via `odb_for_each_object()`

We have multiple callsites where we enumerate all promisor objects in
the object database via `for_each_packed_object()`. This is done by
passing the `ODB_FOR_EACH_OBJECT_PROMISOR_ONLY` flag, which causes us to
skip over all non-promisor objects.

These callsites can be trivially converted to `odb_for_each_object()` as
we know to skip enumeration of loose objects in case the `PROMISOR_ONLY`
flag was passed by the caller.

Refactor the sites accordingly.
