Subject: [PATCH] libmount: initialize *root to NULL in mnt_table_get_root_fs
Date: Sun, 16 Feb 2014 14:58:06 +0100	[thread overview]
Message-ID: <1392559086-4010-1-git-send-email-thomas@archlinux.org> (raw)

mnt_table_get_root_fs only works when *root is set to NULL. This
is not only undocumented, but also unintuitive. Fix it by initializing
*root inside mnt_table_get_root_fs.
