Subject: [folded-merged] ocfs2-fix-null-pointer-dereference-in-ocfs2_dir_foreach_blk_id-fix.patch removed from -mm tree To: dan.carpenter@xxxxxxxxxx,jeff.liu@xxxxxxxxxx,jlbec@xxxxxxxxxxxx,mfasheh@xxxxxxxx,viro@xxxxxxxxxxxxxxxxxx,wb@xxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Tue, 13 Aug 2013 15:57:50 -0700 The patch titled Subject: ocfs2: ocfs2: fix recent memory corruption bug has been removed from the -mm tree. Its filename was ocfs2-fix-null-pointer-dereference-in-ocfs2_dir_foreach_blk_id-fix.patch This patch was dropped because it was folded into ocfs2-fix-null-pointer-dereference-in-ocfs2_dir_foreach_blk_id.patch ------------------------------------------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Subject: ocfs2: ocfs2: fix recent memory corruption bug The pointer math in 6fdf3af1d2 "ocfs2: fix null pointer dereference in ocfs2_dir_foreach_blk_id()" isn't correct so it will zero out the wrong memory. In fact, the memset isn't needed because the initializer will set all these values to zero. This patch also removes the "ctx.pos = 0" initialization because that will be zeroed automatically as well.
