[PATCH 0/2] For improved pack locality

[Junio C Hamano <gitster@pobox.com>]

Shawn kept bugging me about the locality of data in the packfiles
generated by C-git (see pack-heuristics.txt in Documentation/technical)
is often horrible, so here is my stab at it. The idea is to make sure
that the majority of pack accesses fall to nearby locations in the
mmapped packfile to reduce minor faults (which would help if you are
accessing the packfile over slow link like NFS, or starting from a cold
cache).

Junio C Hamano (2):
  core: log offset pack data accesses happened
  pack-objects: optimize "recency order"
