From 3b85739dd6c63c8f94f87d6574494919d2c1119f Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Thu, 14 Feb 2013 10:29:50 -0800 Subject: [PATCH] btrfs-progs: Fix pointer math in __ino_to_path_fd We are casting an array of u64 values into a char ** array so when we dereference this array (as a char **) on a 32 bit system we're then re-casting that back to a 32 bit value. This causes problems when we try to print those strings.
