Subject: [PATCH 5.5 63/65] scsi: target: remove boilerplate code
Date: Mon, 20 Apr 2020 14:39:07 +0200	[thread overview]
Message-ID: <20200420121520.027764023@linuxfoundation.org> (raw)
In-Reply-To: <20200420121505.909671922@linuxfoundation.org>

From: Maurizio Lombardi <mlombard@redhat.com>

[ Upstream commit e49a7d994379278d3353d7ffc7994672752fb0ad ]

iscsit_free_session() is equivalent to iscsit_stop_session() followed by a
call to iscsit_close_session().
