Btrfs devel - Oct 2011 - [PATCH 1/2][BTRFS-PROGS] add the "--force" switch to the mkfs.btrfs command

As requested by Mitch, I resend the patch related to the "--force"
option for
the mkfs.btrfs command.

This patch allow to bypass the check which ensure that you are formatting a 
not mounted partition/disk.
Sometime (eg in a chrooted environment where the /proc filesystem is not 
mounted ) you don''t have all the information, and the check fails even
if the
device is not mounted.

Passing the --force|-f flag to the mkfs.btrfs command you bypass this check.

This patch update the mkfs.c program.

   Could I have your signed-off-by for these two patches, please?
(This one and the subsequent one that does the man pages). I''m also
missing your S-o-B on the man page patch series -- no need to respin
the patches, just supply the relevant S-o-B line that I can put in.

   Thanks,
   Hugo.
