| 4 | Subject: ext4: actually request zeroing of inode table after grow | |
| 5 | ||

| 8 | commit 310a997fd74de778b9a4848a64be9cda9f18764a upstream. | |
| 9 | ||
| 10 | It is never possible, that number of block groups decreases, | |
| 11 | since only online grow is supported. | |
| 12 | ||
| 13 | But after a growing occured, we have to zero inode tables | |
| 14 | for just created new block groups. | |
| 15 | ||
| 16 | Fixes: 19c5246d2516 ("ext4: add new online resize interface") | |
