Subject: [PATCH v2 09/24] expire_reflog(): extract two policy-related functions
Date: Fri, 12 Dec 2014 09:56:48 +0100 [thread overview]
Message-ID: <1418374623-5566-10-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1418374623-5566-1-git-send-email-mhagger@alum.mit.edu>
Extract two functions, reflog_expiry_prepare() and
reflog_expiry_cleanup(), from expire_reflog(). This is a further step
towards separating the code for deciding on expiration policy from the
code that manages the physical deletion of reflog entries.
This change requires a couple of local variables from expire_reflog()
to be turned into fields of "struct expire_reflog_cb". More
reorganization of the callback data will follow in later commits.
