From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Evers Subject: [PATCH V3 0/4] Configure number of LUs reported by 'report-luns' Date: Thu, 7 Mar 2013 08:38:31 -0500 Message-ID: <1362663515-3476-1-git-send-email-revers@redhat.com> Return-path: Received: from mx1.redhat.com ([209.132.183.28]:4464 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932872Ab3CGNil (ORCPT ); Thu, 7 Mar 2013 08:38:41 -0500 Sender: linux-scsi-owner@vger.kernel.org List-Id: linux-scsi@vger.kernel.org To: linux-scsi@vger.kernel.org Cc: revers@redhat.com, michaelc@cs.wisc.edu, bvanassche@acm.org, emilne@redhat.com This patch set retrieves the number of LUs available on a target using the report-luns command. The initial size of the report-luns command is 512 entries, as the previous default initial number was. If more LUs than 511 are present on a target, the report-luns is re-issued with the size indicated in the result of the original report-luns, up to max_report_luns. The default value of max_report_luns is increased to 16k-1 from 512-1. 3rd version changes from 2nd posting: - add a patch to use get/put_unaligned_be32() in report-luns code 2nd version changes from first posting: - Minor tweak added in 2nd patch to use the number of luns reported in the 2nd report-luns command, if it is executed. There is a chance that the number changed between the 1st and 2nd report-luns. - Add 3rd patch changing kmalloc flag in report luns from GFP_ATOMIC to GFP_KERNEL, as this is more consistent with the allocation flag in blk_alloc_queue_node() Rob Evers (4): Encapsulate scsi_do_report_luns Configure reported luns Change kmallocs in report_luns to use GFP_KERNEL Use set/get_unaligned_be32 in report_luns drivers/scsi/scsi_scan.c | 192 +++++++++++++++++++++++++++++------------------ 1 file changed, 120 insertions(+), 72 deletions(-) -- 1.7.11.7
