-Subject: [PATCH] Do not register fake repository as owner of ODB
-
-Accessing ODB is guaranteed to be thread-safe. Registering a
-fake repository (created via git_repository_wrap_odb()) may
-not register itself as owner of the ODB in order to maintain
-that guarantee. Otherwise, accessing objects from ODB will
-try to obtain the cache from the owning repository (via
-odb_cache()) and produce a race if this ODB is concurrently
-used to create fake repositories in other threads.
-Consequently, operations on fake repositories will interact
-with the ODB's cache instead of the repository's cache.
