LIST (provide full path) ======================== DIF/DIX block/blk-integrity.c bna drivers/net/bna/bnad.c bfa (FCoE) drivers/scsi/bfa/bfad_im.c btrfs fs/btrfs/super.c ecryptfs fs/ecryptfs/main.c fscache fs/fscache/main.c I've confirmed the Tech Preview warning shows up in dmesg when all the above modules get loaded, except for DIF/DIX.. It appears that doesn't get built into its own module so I'm not sure if there is any way to test that one.
I added Mike S. to the cc. I used a module param to test the DIF/DIX stuff IIRC, I used (per Mike's suggestion) # modprobe scsi_debug dix=17 dif=1 and it caused the DIF/DIX taint as expected. Cheers, Don
Confirmed scsi_debug with dix=17 dif=1 gives us the expected dmesg warning.
