Hi Niklas,
I just checked on my local git clone of noble master-next:
$ git log --oneline --grep "s390/pci: Allow re-add of a reserved but not yet
removed device"
1c9b1caef9db s390/pci: Allow re-add of a reserved but not yet removed device
$ git tag --contains 1c9b1caef9db
Ubuntu-6.8.0-64.67 <=====
Ubuntu-lowlatency-6.8.0-64.67.1
fheimes@T570:~/ubuntu-noble-master-next/noble-clean$ git show 1c9b1caef9db |
grep -C 3 zpci_event_reappear
zdev->state = ZPCI_FN_STATE_STANDBY;
}
+static void zpci_event_reappear(struct zpci_dev *zdev)
+{
+ lockdep_assert_held(&zdev->state_lock);
+ /*

}
} else {
+ if (zdev->state == ZPCI_FN_STATE_RESERVED)
+ zpci_event_reappear(zdev);
/* the configuration request may be stale */
- if (zdev->state != ZPCI_FN_STATE_STANDBY)
+ else if (zdev->state != ZPCI_FN_STATE_STANDBY)

}
} else {

+ zpci_event_reappear(zdev);
zpci_update_fh(zdev, ccdf->fh);
}
break;

--suite=noble,noble-proposed --arch=s390x linux-generic
linux-generic | 6.8.0-31.31 | noble | s390x
linux-generic | 6.8.0-64.67 | noble-proposed | s390x <=====
So the code is included in: 6.8.0-64.67
On the git web interface I think it's this link:
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble/log/?h=master-next&qt=grep&q=s390%2Fpci%3A+Allow+re-add+of+a+reserved+but+not+yet+removed+device

(so using normal master-next (master-next):
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble/log/?h=master-next
instead of:
master-next--2025.06.16-2--auto )
