From c27d89f959fa1ace47e03517d037477ce7f7de96 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Wed, 13 Mar 2013 10:37:27 -0500 Subject: btrfs-progs: document force option in mkfs usage(); add long opt I missed updating the mkfs.btrfs usage() when I added the option to force fs overwrite. Update that, and while we're at it add a long option, since all other commands have long counterparts.
