Subject: [PATCH v3 05/30] packed_ref_store: move `packed_refs_lock` member here
Date: Sat, 1 Jul 2017 20:30:43 +0200 [thread overview]
Message-ID: <ffe9dd89adb2b342ea379f2644ed965aa8d89ffb.1498933362.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1498933362.git.mhagger@alum.mit.edu>
Move the `packed_refs_lock` member from `files_ref_store` to
`packed_ref_store`, and rename it to `lock` since it's now more
obvious what it is locking.
