From 84167d190569eedcdb24bf2499bdda437e442962 Mon Sep 17 00:00:00 2001 From: Stefan Behrens Date: Thu, 11 Oct 2012 07:25:16 -0600 Subject: [PATCH] Btrfs: Fix wrong error handling code gcc says "warning: comparison of unsigned expression >= 0 is always true" because i is an unsigned long. And gcc is right this time.
