From eec11535ca3d3e2daa2c8f59fa8ce1963db98abd Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 18 Jan 2017 14:13:20 +0300 Subject: [PATCH] hfs: fix hfs_readdir() I was looking through static analysis warnings and there is a bug here that goes all the way back to the start of git. Basically we're copying the pointer and nearby garbage instead of the data the fd.key pointer is pointing to.
