REQ_OP_WRITE_SAME was only ever submitted by the legacy Linux zeroing code, which has switched to use REQ_OP_WRITE_ZEROES long before rnbd was even merged. Link: https://lore.kernel.org/r/20220209082828.2629273-4-hch@lst.deReviewed-by:

The write_same and write_zeroes limits for SCSI are effectively the same, so the current code works just fine. But we plan to remove REQ_OP_WRITE_SAME support, so switch to querying the write zeroes limit for a zeroing WRITE SAME operation.

Make cmd_ring_size changeable similar to the way it is done for max_data_area_mb. The reason is that our tcmu client will create thousands of tcmu instances, and this will consume lots of mem with default 8Mb cmd ring size for every backstore. One can change the value by typing: echo "cmd_ring_size_mb=N" > control The "N" is a integer between 1 to 8, if set 1, the cmd ring can hold about 6k cmds(tcmu_cmd_entry about 176 byte) at least. The value is printed when doing: cat info In addition, a new readonly attribute 'cmd_ring_size_mb' returns the value in read.

Remove struct scsi_pointer from struct scsi_cmnd since the previous patches removed all users of that member of struct scsi_cmnd. Additionally, reorder the members of struct scsi_cmnd such that the statement that the field below can be modified by the SCSI LLD is again correct.

Set scsi_host_template.cmd_size instead of using the SCSI pointer for storing driver-private data. Change the type of the argument of uas_add_work() from struct uas_cmd_info * into struct scsi_cmnd * because it is easier to convert a SCSI command pointer into a uas_cmd_info pointer than the other way around.

Instead of using the SCp.ptr field to track whether or not a command is in flight, use the sp->type field to track this information. sp->type must be set for proper operation of the qla2xxx driver.

Instead of storing the iSCSI task pointer and the session age in the SCSI pointer, use command-private variables. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd. The list of iSCSI drivers has been obtained as follows: $ git grep -lw iscsi_host_alloc drivers/infiniband/ulp/iser/iscsi_iser.c drivers/scsi/be2iscsi/be_main.c drivers/scsi/bnx2i/bnx2i_iscsi.c drivers/scsi/cxgbi/libcxgbi.c drivers/scsi/iscsi_tcp.c drivers/scsi/libiscsi.c drivers/scsi/qedi/qedi_main.c drivers/scsi/qla4xxx/ql4_os.c include/scsi/libiscsi.h Note: it is not clear to me how the qla4xxx driver can work without this patch since it uses the scsi_cmnd::SCp.ptr member for two different purposes: - The qla4xxx driver uses this member to store a struct srb pointer. - libiscsi uses this member to store a struct iscsi_task pointer.
