| Subject: [PATCH 28/85] ext4: Always set dx_node's fake_dirent explicitly. |
| |
| (cherry picked from commit 1f7bebb9e911d870fa8f997ddff838e82b5715ea) |
| |
| When ext4_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. |
