Subject: [PATCH 3/7] nvme: open code nvme_put_ns_from_disk in nvme_ns_head_ctrl_ioctl
Date: Thu, 20 May 2021 07:44:22 +0200 [thread overview]
Message-ID: <20210520054426.567241-4-hch@lst.de> (raw)
In-Reply-To: <20210520054426.567241-1-hch@lst.de>
nvme_ns_head_ctrl_ioctl is always used on multipath nodes, so just call
srcu_read_unlock directly.
