Subject: [PATCH 10/14] btrfs: Remove root argument of cleanup_transaction
Date: Wed, 7 Feb 2018 17:55:46 +0200 [thread overview]
Message-ID: <1518018950-31456-11-git-send-email-nborisov@suse.com> (raw)
In-Reply-To: <1518018950-31456-1-git-send-email-nborisov@suse.com>
The only thing the passed root is used for is:
1. get a reference to the fs_info and to
2. call trace_btrfs_transaction_commit.
We can achieve 1) by simply referring to the fs_info from passed trans
object. As far as 2) is concerned cleanup_transaction is called from
only one place and the 'root' argument passed is the one from the trans
handle. No functional changes.
