From 3b96fc2ea791adfaeef265854d3a58259a0d3f19 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 22 Oct 2009 00:43:19 -0400 Subject: sysctl: avoid inline initialization Assign each field one by one rather than stack initialization as gcc will call memset() to zero out the rest of the structure -- which we don't care about as the field is unused and not seen outside of the libc.
