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.

It seems like some important info from the original ticket is missing, which is that I believe I already know the 2 commits which resolve this issue:


1e6db2ee86e6a4399fc0ae5689e55e0fd1c43caf
1e5b0cf8672e622257df024074e6e09bfbcb7750

I simply want to know how soon this will be fixed, so I know whether I need to build and maintain a patched RPM myself, or if I can just wait for RHEL to offer the fix.

Hello Gregg. This issue has been already fixed in RHEL-7 and the bits are under testing right now. The fixed package will be released within RHEL-7.8.
Closing this bug as a dupe of bz1757325 which I filed based on your e-mail report and which tracks the issue already. I've also made the mentioned bug public.
