From 33cc559a81397bc813c392617d40ddfdfa3cffbd Mon Sep 17 00:00:00 2001 From: Tomas Jasek Date: Fri, 3 Mar 2017 13:45:48 +0100 Subject: scsi: lpfc: replace init_timer by setup_timer This patch shortens every init_timer in lpfc module followed by function and data assignment using setup_timer. This is purely cleanup patch, it does not add new functionality nor remove any existing functionality. An init_timer call in this form: init_timer(&vport->fc_disctmo); vport->fc_disctmo.function = lpfc_disc_timeout; vport->fc_disctmo.data = vport; is shortened to: setup_timer(&vport->fc_disctmo, lpfc_disc_timeout, vport); It increases readability and reduces chances of mistakes done by developers.

This patch adds abort path support, modeled after the SCSI code paths. Currently addresses only the initiator path. Target path under development, but stubbed out.
