Subject: [PATCH] setfacl --restore: Silence valgrind
Valgrind complains that setfacl --restore triggers uninitialized memory
accesses to cmd->c_tag and cmd->c_perm of CMD_REMOVE_ACL commands in
do_set (http://savannah.nongnu.org/bugs/?50566). In this case, the
uninitialized memory accesses have no effect. Silence valgrind by
initializing cmd->c_tag and cmd->c_perm anyway.
