Function btrfs_scan_devices() is being used by commands such as 'btrfs filesystem' and 'btrfs device', by having the verbose argument in the btrfs_scan_devices() we can control which threads to print the messages when verbose is enabled by the global option. Add an option %verbose to btrfs_scan_devices(). Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>
