Subject: [PATCH v2 2/6] btrfs: Remove fs_info from struct async_cow
Date: Wed, 20 Feb 2019 17:11:39 +0200 [thread overview]
Message-ID: <20190220151143.19057-3-nborisov@suse.com> (raw)
In-Reply-To: <20190220151143.19057-1-nborisov@suse.com>
We always pass an inode alongside async_cow. fs_info can be referenced
from this inode so it makes the explicit fs_info member in
struct async_cow redundant, remove it. No functional changes.
