From b44445131fee871f169adf18b74093b38f5bae32 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney <jeffm@suse.com> Date: Tue, 6 Mar 2018 21:24:46 -0500 Subject: [PATCH] btrfs-progs: pass cmd_struct to command callback function This patch passes the cmd_struct to the command callback function. This has several purposes: It allows the command callback to identify which command was used to call it. It also gives us direct access to the usage associated with that command.
