Subject: [PATCH 7/7] btrfs: btrfs_dev_replace_update_device_in_mapping_tree drop file global declare
Date: Fri, 14 Aug 2020 08:03:52 +0800	[thread overview]
Message-ID: <20200814000352.124179-8-anand.jain@oracle.com> (raw)
In-Reply-To: <20200814000352.124179-1-anand.jain@oracle.com>

There isn't any convoluted child functions inside the
btrfs_dev_replace_update_device_in_mapping_tree() function. With the
function moved before where it is called, we can drop its file local
declare.

No functional changes.
