+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.
