[Fix] * backport commit "block: Move checking GENHD_FL_NO_PART to bdev_add_partition()" [Test Plan] * dd if=/dev/zero of=/tmp/foo bs=1M count=50 * partprobe $(losetup --find --show /tmp/foo) Before the fix this fails. After the fix it should work. [Where problems could occur] * We may see issues on disk partitions operations. Old description: This is with the kernel from jammy-proposed (linux-image-5.15.0-94-generic 5.15.0-94.104). Do this: # dd if=/dev/zero of=/tmp/file bs=1M count=50 # partprobe "$(losetup --show --find /tmp/file)" Notice this very odd error message: Error: Partition(s) 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64 on /dev/loop2 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. That's a result of an ioctl changing its error code in an incompatible way between kernel versions 5.15.0.91.88 and 5.15.0.94.91, confusing partprobe. 5.15.0.91.88: ioctl(3, BLKPG, {op=BLKPG_DEL_PARTITION, flags=0, datalen=152, data={start=0, length=0, pno=1, devname="", volname=""}}) = -1 ENXIO (No such device or address) 5.15.0.94.91: ioctl(3, BLKPG, {op=BLKPG_DEL_PARTITION, flags=0, datalen=152, data={start=0, length=0, pno=1, devname="", volname=""}}) = -1 EINVAL (Invalid argument) This is a userspace API break which impacts GNU parted and util-linux (as confirmed by the util-linux maintainer).
