From 103fb6d43bd6ec7049564cc39e4c0e495f9bfcb8 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 18 Oct 2019 01:01:26 -0400 Subject: fsck: accept an oid instead of a "struct tag" for fsck_tag() We don't actually look at the tag struct in fsck_tag() beyond its oid and type (which is obviously OBJ_TAG). Just taking an oid gives our callers more flexibility to avoid creating or parsing a struct, and makes it clear that we are fscking just what is in the buffer, not any pre-parsed bits from the struct.
