[JGIT PATCH (RESEND) 0/4] Fix race condition on loading pack files

I had sent this series while you were on vacation, so I assume it just got lost in the shuffle and am resending.

This series tries to fix a "racy git" problem when reading pack files in a repository; its possible that the directory is modified, read and modified again in the same filesystem timestamp, resulting in the reader not noticing the second modification. This may cause a reader to lose access to objects on disk.

Shawn O. Pearce (4):
  Avoid unnecessary stat when scanning packs in the objects directory
  Make ObjectDirectory last modified time atomically updated with list
  Don't create new pack lists if the directory hasn't changed
  Fix racy condition when a repository is repacked
