From 3c7d76e371ac1a3802ae1673f5c63554af59325c Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 29 Oct 2009 08:56:19 -0600 Subject: param: fix setting arrays of bool We create a dummy struct kernel_param on the stack for parsing each array element, but we didn't initialize the flags word. This matters for arrays of type "bool", where the flag indicates if it really is an array of bools or unsigned int (old-style).
