Subject: sfdisk: allow partitioning drives of over 2^31 sectors.
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5119dec449a8d7c07bf01947e957b862035e1260;p=util-linux

sfdisk: allow partitioning drives of over 2^31 sectors.

sfdisk would incorrectly complain that there was no room when partitioning
a drive over 2^31 sectors in size.
