partx: add --sector-size option
/dev/sdc is 4K disk:
# fdisk -l /dev/sdc
Disk /dev/sdc: 100 MiB, 104857600 bytes, 25600 sectors
...
Device Boot Start End Sectors Size Id Type
/dev/sdc1 1024 25599 24576 96M 83 Linux
let's use it as disk image:
# dd if=/dev/sdc of=~/sdc.img
# losetup -f ~/sdc.img
old version:
# partx --show /dev/loop0
NR START END SECTORS SIZE NAME UUID
1 1024 25599 24576 12M 6a4ba75b-01
new version:
# partx --show /dev/loop0 --sector-size 4096
NR START END SECTORS SIZE NAME UUID
