Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock. @exclude is used to record which type of rwsem we are holding. Signed-off-by:

A race condition may happen if two threads are both trying to open the same sg with O_EXCL simultaneously. It's possible that they both find fsds list is empty and get_exclude(sdp) returns 0, then they both call set_exclude() and break out from wait_event_interruptible and resume open. Now use rwsem to protect this process. Exclusive open gets write lock and others get read lock. The lock will be held until file descriptor is closed. This also leads 'exclude' only a status rather than a check mark. Signed-off-by:

Commit b90ebc3d ("[SCSI] scsi_debug: fix logical block provisioning support") fixed several issues with logical block provisioning support, but it still doesn't properly fix the cases when unmap_alignment > 0. For example, load scsi_debug module with the following module parameters and make all blocks mapped by filling the storage with zero. # modprobe scsi_debug lbpu=1 unmap_alignment=1 unmap_granularity=4 # dd if=/dev/zero of=$DEV Then, try to unmap the first unmappable blocks at lba=1, but GET LBA STATUS unexpectedly reports that the last UNMAP has done nothing. # sg_unmap --lba=1 --num=4 $DEV # sg_get_lba_status --lba=1 $DEV descriptor LBA: 0x0000000000000001 blocks: 16383 mapped The problem is in map_index_to_lba(), which should return the first LBA which is corresponding to a given index of provisioning map (map_storep).

With module parameter num_parts > 0, partition table is built on the ramdisk storage when loading the driver. Unfortunately, there is an endianness bug in sdebug_build_parts(). So the partition table is not correctly initialized on big-endian systems. Signed-off-by:

Earlier IDC-TIME-EXTEND aen was a nop and ignored by driver. We now have to handle the aen so that other protocol drivers can use time extension during some loopback operations. Signed-off-by:

The patch changes a specifier used to output some variables. Instead of using stack for each byte the '%*ph[CN]' allows to take a one pointer and prints entire buffer as a hexadecimal string with the separator ':' or ''. Signed-off-by:
