Reported by a user on IRC, I verified it on one of my old test boxes.
The function is missing in older versions of blkid and causes comilation
errors:
[CC] utils.o
utils.c: In function ‘wipe_existing_fs’:
utils.c:705:3: warning: implicit declaration of function ‘blkid_do_wipe
utils.o: In function `wipe_existing_fs':
/labs/dsterba/btrfs-progs/utils.c:705: undefined reference to `blkid_do_wipe'
collect2: ld returned 1 exit status
blkid_do_wipe is from Novembe 2011, so nothing really new, but I'd still
like to keep the backward compatibility of btrfs-progs. The
implementation of blkid_do_wipe uses some internal data so it's not
possible to simply copy the implementation. Maybe wiping the first
megabyte is enough.
