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.
Fixed with upstream commit 6fb025a:
<https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commit;h=6fb025aaaa355a8d93dc1ea720007a22665c7659>
====
Fixed BZ1160837 by updating the iostat-scsi.stp example.
* testsuite/systemtap.examples/io/iostat-scsi.stp: Updated for newer
kernels like RHEL7 and rawhide. Probes the "sd_init_command" kernel
function which replaced "sd_prep_fn" in newer kernels. Added whitespace
for more clarity.
====
Tested under RHEL6 (x86_64, ppc64, s390x), RHEL7 (x86_64, ppc64, s390x), and rawhide (x86_64).
The problem was that the upstream kernel had renamed the 'sd_prep_fn()' to 'sd_init_command()'. Also worked around an issue with missing parameter debuginfo on an inlined function on ppc64.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory, and where to find the updated

Please be aware that every RHEL has a different release cycle. This bug was timely fixed for the release it was scheduled for [RHEL 7].
If you are a customer your sales or support account representative can help you open a customer case an escalate the issue for a faster turn around for high priority / critical issues.
