Subject: [PATCH 07/11] apply: remove `newfd` from `struct apply_state`
Date: Sun, 1 Oct 2017 16:56:08 +0200 [thread overview]
Message-ID: <cede314e90ece6e4168634f5469f6c6f9883e375.1506862824.git.martin.agren@gmail.com> (raw)
In-Reply-To: <cover.1506862824.git.martin.agren@gmail.com>
Similar to a previous patch, we do not need to use `newfd` to signal
that we have a lockfile to clean up. We can just unconditionally call
`rollback_lock_file`. If we do not hold the lock, it will be a no-op.
Where we check `newfd` to decide whether we need to take the lock, we
can instead use `is_lock_file_locked()`.
