[Expected Results]
IO running normally
[Reproducibility]
occasionally
[Additional information]
Hardware: D06 CS
Firmware: NA+I59
Kernel: NA
[Resolution]
Variable dif in function sd_setup_read_write_cmnd() is the return value of
function scsi_host_dif_capable() which returns dif capability of disks. If
define it as bool, even for the disks which support DIF3, the function
still return dif=1, which causes IO error. So define variable dif as
unsigned int instead of bool.
scsi: sd: define variable dif as unsigned int instead of bool
