Petersen" Cc: Christoph Hellwig , James Bottomley , linux-scsi@vger.kernel.org, Hannes Reinecke Subject: [PATCHv4 0/9] scsi: remove legacy cmd_list implementation Date: Mon, 18 Nov 2019 10:21:59 +0100 Message-Id: <20191118092208.54521-1-hare@suse.de> X-Mailer: git-send-email 2.16.4 Sender: linux-scsi-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Hi all, with the switch to blk-mq we have an efficient way of looking up outstanding commands via blk_mq_rq_busy_iter(). In this patchset the dpt_i2o and aacraid drivers are switched over to using that function, and the now obsolete cmd_list implemantation in the SCSI midlayer is removed. As usual, comments and reviews are welcome. Changes to v1: - Fixup kbuild warning Changes to v2: - Add scsi_host_busy_iter() - Include reviews from Christoph Changes to v3: - Include reviews from Christoph - Add midlayer helper to terminate outstanding commands - Split off aacraid modifcations into several patches Hannes Reinecke (9): dpt_i2o: rename adpt_i2o_to_scsi() to adpt_i2o_scsi_complete() scsi: add scsi_host_flush_commands() helper dpt_i2o: use scsi_host_flush_commands() to abort outstanding commands aacraid: Do not wait for outstanding write commands on synchronize_cache aacraid: use midlayer helper to terminate outstanding commands scsi: add scsi_host_busy_iter() aacraid: use scsi_host_busy_iter() in aac_wait_for_io_completion() aacraid: use scsi_host_busy_iter() in get_num_of_incomplete_fibs() scsi: Remove cmd_list functionality drivers/scsi/aacraid/aachba.c | 76 +------------------------------------- drivers/scsi/aacraid/comminit.c | 30 +++++++-------- drivers/scsi/aacraid/commsup.c | 24 +----------- drivers/scsi/aacraid/linit.c | 81 +++++++++++++++++++++-------------------- drivers/scsi/dpt_i2o.c | 25 ++----------- drivers/scsi/dpti.h | 3 +- drivers/scsi/hosts.c | 57 +++++++++++++++++++++++++++++ drivers/scsi/scsi.c | 14 ------- drivers/scsi/scsi_error.c | 1 - drivers/scsi/scsi_lib.c | 31 ---------------- drivers/scsi/scsi_priv.h | 2 - drivers/scsi/scsi_scan.c | 1 - include/scsi/scsi_cmnd.h | 1 - include/scsi/scsi_device.h | 1 - include/scsi/scsi_host.h | 8 +++- 15 files changed, 125 insertions(+), 230 deletions(-)
