Subject: [PATCH 15/20] btrfs-progs: pass cmd_struct to clean_args_no_options{,_relaxed}
Date: Wed,  7 Mar 2018 21:40:42 -0500	[thread overview]
Message-ID: <20180308024047.10104-16-jeffm@suse.com> (raw)
In-Reply-To: <20180308024047.10104-1-jeffm@suse.com>

From: Jeff Mahoney <jeffm@suse.com>

Now that we have a cmd_struct everywhere, we can pass it to
clean_args_no_options and have it resolve the usage string from
it there.  This is necessary for it to pass the cmd_struct to
usage() in the next patch.
