Hi gurus,

When resizing a partition, on first attempt it uses up the whole disk.
Only on second attempt it resizes to the correct target size.
Resizing from any smaller size to a larger size initially uses up the
whole disk, like if -s was not used at all even if it's as little as
one logical disk block.
I'm wondering if anyone else can reproduce.
I just tried to perform the same on an old 8.2-STABLE machine and it
did not behave the same. Growing a partition worked fine on initial
attempts.
