| Subject: ext4: actually request zeroing of inode table after grow |
| |
| From: Kirill Tkhai <ktkhai@virtuozzo.com> |
| |
| commit 310a997fd74de778b9a4848a64be9cda9f18764a upstream. |
| |
| It is never possible, that number of block groups decreases, |
| since only online grow is supported. |
| |
| But after a growing occured, we have to zero inode tables |
| for just created new block groups. |
| |
| Fixes: 19c5246d2516 ("ext4: add new online resize interface") |
