Kernel 5.15.0-97.107 resolves the issue for the test case documented in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2052842
However, I still see a regression with the following test case: $ fallocate -l 1G /tmp/blob $ sudo losetup $LOOPDEV /tmp/blob $ sudo /usr/sbin/parted -s -m -a optimal $LOOPDEV -- unit KiB mklabel gpt mkpart primary 0% 100% Error: Partition(s) 1 on /dev/loop3 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes. Expected results: parted return code is 0, partition is available at ${LOOPDEV}p1 Actual results: parted return code is 1, partition is not available at ${LOOPDEV}p1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2049689 Title: partprobe is broken on empty loopback device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2049689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
