Subject: [PATCH v2 84/84] scsi: core: Call scsi_done directly
Date: Wed, 29 Sep 2021 15:11:35 -0700	[thread overview]
Message-ID: <20210929221138.3511208-5-bvanassche@acm.org> (raw)
In-Reply-To: <20210929220600.3509089-1-bvanassche@acm.org>

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly. Since this patch removes the last user of the
scsi_done member, also remove that data structure member.
