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 Changes to v5: - Add reviews from Balsundar P. - Rename scsi_host_flush_commands() - Replace patch using scsi_host_quiesce() by using busy iterator Changes to v6: - Add reviews from Balsundar P. Changes to v7: - Add reviews from Christoph Hannes Reinecke (13): dpt_i2o: rename adpt_i2o_to_scsi() to adpt_i2o_scsi_complete() scsi: add scsi_host_complete_all_commands() helper dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commands aacraid: Do not wait for outstanding write commands on synchronize_cache aacraid: use scsi_host_complete_all_commands() to terminate outstanding commands aacraid: replace aac_flush_ios() with midlayer helper aacraid: move scsi_(block,unblock)_requests out of _aac_reset_adapter() scsi: add scsi_host_(block,unblock) helper function aacraid: use scsi_host_(block,unblock) to block I/O scsi: add scsi_host_busy_iter() aacraid: use scsi_host_busy_iter() to wait for outstanding commands 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 | 46 +++------------ drivers/scsi/aacraid/linit.c | 120 ++++++++++++++++------------------------ drivers/scsi/dpt_i2o.c | 25 +-------- drivers/scsi/dpti.h | 3 +- drivers/scsi/hosts.c | 65 ++++++++++++++++++++++ drivers/scsi/scsi.c | 14 ----- drivers/scsi/scsi_error.c | 1 - drivers/scsi/scsi_lib.c | 61 ++++++++++---------- 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 | 9 ++- 15 files changed, 181 insertions(+), 279 deletions(-)
