Command (m for help): The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)

WARNING: If you have created or modified any DOS 6.x
partitions, please see the fdisk manual page for additional
information.

Error: Error informing the kernel about modifications to partition /dev/mmcblk0p8 -- Invalid argument. This means Linux won't know about any changes you made to /dev/mmcblk0p8 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.
