From cfd1893477fa94bb0915e39afa2f044ac978b5c6 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 6 Dec 2006 20:37:38 -0800 Subject: [PATCH] [PATCH] ktime: Fix signed / unsigned mismatch in ktime_to_ns The 32 bit implementation of ktime_to_ns returns unsigned value, while the 64 bit version correctly returns an signed value. There is no current user affected by this, but it has to be fixed, as ktime values can be negative.
