RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Don Zickus 2011-03-21 19:27:57 UTC 
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.

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 18:33:57 UTC 
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 18:41:55 UTC 
Confirmed scsi_debug with dix=17 dif=1 gives us the expected dmesg warning.
