Subject: [PATCH 10/15] btrfs: open code list_head pointer in btrfs_init_dev_replace_tgtdev
Date: Thu, 3 Sep 2020 08:57:46 +0800 [thread overview]
Message-ID: <25473568cb1a09ef14821a554055d9dffb009d3f.1599091832.git.anand.jain@oracle.com> (raw)
In-Reply-To: <cover.1599091832.git.anand.jain@oracle.com>
In the function btrfs_init_dev_replace_tgtdev(), the local
variable struct list_head *devices is used only once, instead
just open code the same.
