Subject: [PATCH] btrfs: remove redundant code
Date: Fri, 23 Sep 2022 22:56:12 +0800	[thread overview]
Message-ID: <CAPm50a+6tGRCkB7=QiA+y5EEPm_40N6d-KChPxnT+40Q=5EUQw@mail.gmail.com> (raw)

From: Peng Hao <flyingpeng@tencent.com>

Since leaf is already NULL, and no other branch will go fail_unlock,
the fail_unlock branch is useless.
