[[PATCH v2] 0/4] Use header data patch ids for rebase to avoid loading file content

This patch series is to remove the hand rolled hashmap in the patch_ids and use the hashmap.h implementation. It also introduces the idea of having a header only patch id so that the contents of the files do not have to be loaded in order to determine if two commits are different.

Kevin Willford (4):
  patch-ids: stop using a hand-rolled hashmap implementation
  patch-ids: replace the seen indicator with a commit pointer
  patch-ids: add flag to create the diff patch id using header only data
  rebase: avoid computing unnecessary patch IDs
