| Subject: ext3: Always set dx_node's fake_dirent explicitly. |
| |
| From: Eric Sandeen <sandeen@redhat.com> |
| |
| commit d7433142b63d727b5a217c37b1a1468b116a9771 upstream. |
| |
| (crossport of 1f7bebb9e911d870fa8f997ddff838e82b5715ea |
| by Andreas Schlick <schlick@lavabit.com>) |
| |
| When ext3_dx_add_entry() has to split an index node, it has to ensure that |
| name_len of dx_node's fake_dirent is also zero, because otherwise e2fsck |
| won't recognise it as an intermediate htree node and consider the htree to |
| be corrupted. |
