Public bug reported:
In util-linux libfdisk/src/partition.c
line:1082
function recount_resize()
the partition table that is passed on to the next function
resize_get_last_possible()
should be sorted in order based on their start sectors and not on their
partition numbers.
take this example:
partition are present in this order on the disk:
num start end size
1 0 10 11
4 11 21 10
5 22 30 9
2 31 40 10
freespace 41 60 20
in this case the resize of only partition number 2 to a size 25 will
fail since the
check will find the max size to be part of partition 2 since it finds
no freespace
between 2 and end of disk.
Current check goes in order of partitions and will return once it finds
that next partition
after 2 is 4 and sets the max possible size for 2 as 10.
To prevent this scenario before sending the partition table for the
check it should be sorted
according to the partition starts.
