When expanding a device zfs needs to rescan the partition table to get the correct size. This can only happen when we're in the kernel and requires the device to be closed. As part of the rescan, udev is notified and the device links are removed and recreated. This leave a window where the vdev code may try to reopen the device before udev has recreated the link. If that happens, then the pool may end up in a suspended state. To correct this, we leverage the BLKPG_RESIZE_PARTITION ioctl which allows the partition information to be modified even while it's in use. This ioctl also does not remove the device link associated with the zfs data partition so it eliminates the race condition that can occur in the kernel.
