From bcaa992975041e40449be8c010c26192b8c8b409 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 31 Aug 2011 11:58:51 -0400 Subject: [PATCH] ext4: ext4_rename should dirty dir_bh with the correct directory When ext4_rename performs a directory rename (move), dir_bh is a buffer that is modified to update the '..' link in the directory being moved (old_inode). However, ext4_handle_dirty_metadata is called with the old parent directory inode (old_dir) and dir_bh, which is incorrect because dir_bh does not belong to the parent inode. Fix this error.
