From 09a46c6e34ba152169b7400d266d2efb4c391a43 Mon Sep 17 00:00:00 2001 From: Swen Schillig Date: Tue, 18 Aug 2009 15:43:16 +0200 Subject: [SCSI] zfcp: Remove the useless ZFCP_REQ_AUTO_CLEANUP flag The flag ZFCP_REQ_AUTO_CLEANUP was useless as the ZFCP_STATUS_FSFREQ_CLEANUP flag is there for exactly the same purpose.
