From f1672e50c7f73cbdb1d9817e126c41a3db6d93ce Mon Sep 17 00:00:00 2001 From: Gui Hecheng Date: Wed, 16 Jul 2014 11:59:46 +0800 Subject: btrfs-progs: use check_argc_* to check arg number for all tools Since this patch: btrfs-progs: move the check_argc_* functions into utils.c All tools including the independent tools(e.g. btrfs-image, btrfs-convert) can share the convenience of the check_argc_* functions, so this patch adopt the argc check functions globally.
