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 Jeff Moyer 2021-05-25 16:27:07 UTC
Description of problem:
io_uring is not yet ready for enterprise use.  Disable it for now.

Comment 1 Jeff Moyer 2021-05-26 20:08:27 UTC
QE: To verify support is disabled, you can run any program which makes use of io_uring.  The program should fail upon trying to create the ring.  The io_uring_setup system call should return ENOSYS.  Example programs include fio's t/io_uring, or fio itself.  This needs to be completed before beta freeze.

> Herton, do you know why this bug is still in post?

It's merged on kernel-ark, but not synced yet to centos/rhel9.
I was on pto but plan to resume syncing this week, which should
bring this into rhel9, once I sync I'll move this to MODIFIED.
I'm also moving DTM/ITM forward to adjust since it's already
passed.
