[Cluster-devel] [PATCH] mkfs: Remove duplicated code from verify_bsize()

[Carlos Maiolino <cmaiolino@redhat.com>]

Although are_you_sure() function adds some little extra overhead due some
extra checks, use this function instead of duplicate code is worth.
The extra security checks and the additional overhead will not be
noticed by the user.

This is the first try of this patch, but I think the good way to do that
is to move are_you_sure() and some related functions to libgfs2.
