Description Don Zickus 2011-03-21 15:27:57 EDT 
Description of problem:

Need to mark drivers in the kernel as tech preview.  I put together a patch that utilizes the infrastructure already in place.

This will help with certification and flag modules and features that are loaded to prevent certification from succeeding.

Comment 6 Mike Gahagan 2011-04-12 14:25:10 EDT 
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.
Comment 7 Don Zickus 2011-04-12 14:33:57 EDT 
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
Comment 8 Mike Gahagan 2011-04-12 14:41:55 EDT 
Confirmed scsi_debug with dix=17 dif=1 gives us the expected dmesg warning.
