From: Martin Wilck <mwilck@xxxxxxxx> This patch series addresses some issues we saw in a test setup with a large number of SCSI LUNs. The first two patches simply increase the number of available sg and bsg devices. 3-5 fix a large delay we encountered between blocking a Fibre Channel remote port and the dev_loss_tmo. 6 renames scsi_target_block() to scsi_block_targets(), and makes additional changes to this API, as suggested in the review of the v2 series. Changes v3 -> v4: - skipped 4/8: keep state_mutex held while quiescing queue (Bart van Assche), added a comment in 4/6 to explain the rationale - renamed scsi_target_block() to scsi_block_targets() (Christoph Hellwig), and merged the previous patches 7/8 and 8/8 modifying this API into 6/6. - rebased to latest mkp/queue branch Changes v2 -> v3: - Split previous 3/3 into 4 separate patches as suggested by Christoph Hellwig. - Added 7/8 and 8/8, as suggested by Christoph and Bart van Assche. - Added s-o-b and reviewed-by tags. Changes v1 -> v2: - call blk_mq_wait_quiesce_done() from scsi_target_block() to cover the case where BLK_MQ_F_BLOCKING is set (Bart van Assche) Hannes Reinecke (2): bsg: increase number of devices scsi: sg: increase number of devices Martin Wilck (4): scsi: merge scsi_internal_device_block() and device_block() scsi: don't wait for quiesce in scsi_stop_queue() scsi: don't wait for quiesce in scsi_device_block() scsi: replace scsi_target_block() by scsi_block_targets() block/bsg.c | 2 +- drivers/scsi/scsi_lib.c | 76 ++++++++++++++--------------- drivers/scsi/scsi_transport_fc.c | 2 +- drivers/scsi/scsi_transport_iscsi.c | 3 +- drivers/scsi/scsi_transport_srp.c | 6 +-- drivers/scsi/sg.c | 2 +- drivers/scsi/snic/snic_disc.c | 2 +- include/scsi/scsi_device.h | 2 +- 8 files changed, 46 insertions(+), 49 deletions(-) -- 2.40.1
