Akinobu Mita b90ebc3d5c [SCSI] scsi_debug: fix logical block provisioning support ... provisioning map (map_storep) is a bitmap accessed by bitops. So the allocation size should be a multiple of sizeof(unsigned long) and also the bitmap should be cleared by using bitmap_clear() instead of memset(). Otherwise it will cause problem on big-endian architecture if the number of bits is not a multiple of BITS_PER_LONG. I tried testing the logical block provisioning support in scsi_debug, but it didn't work as I expected. For example, load scsi_debug module with UNMAP command supported and fill the storage with random data. # modprobe scsi_debug lbpu=1 # dd if=/dev/urandom of=/dev/sdb Then, try to unmap LBA 0, but Get LBA status reports: # sg_unmap --lba=0 --num=1 /dev/sdb # sg_get_lba_status --lba=0 /dev/sdb descriptor LBA: 0x0000000000000000 blocks: 16384 mapped This is unexpected result. Because UNMAP command to LBA 0 finished without any errors, but Get LBA status shows that LBA 0 is still mapped. This problem is due to the wrong translation between LBA and index of provisioning map. Fix it by using correct translation functions.
