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 Changes to v4: - Include reviews from Bart - Add new midlayer helper scsi_host_quiesce()/scsi_host_resume() - Improve comments Hannes Reinecke (11): 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 aacraid: replace aac_flush_ios() with midlayer helper scsi: add scsi_host_quiesce()/scsi_host_resume() helper aacraid: use scsi_host_quiesce() to wait for I/O to complete scsi: add scsi_host_busy_iter() 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 | 35 +------------- drivers/scsi/aacraid/commsup.c | 24 +-------- drivers/scsi/aacraid/linit.c | 105 ++++++++++++++++------------------------ drivers/scsi/dpt_i2o.c | 25 ++-------- drivers/scsi/dpti.h | 3 +- drivers/scsi/hosts.c | 62 ++++++++++++++++++++++++ drivers/scsi/scsi.c | 14 ------ drivers/scsi/scsi_error.c | 1 - drivers/scsi/scsi_lib.c | 49 +++++++------------ drivers/scsi/scsi_priv.h | 2 - drivers/scsi/scsi_scan.c | 1 - include/scsi/scsi_cmnd.h | 1 - include/scsi/scsi_device.h | 3 +- include/scsi/scsi_host.h | 8 ++- 15 files changed, 141 insertions(+), 268 deletions(-) -- 2.16.4
