| Subject: ext4: remove check for zero nr_to_scan in ext4_es_scan() |
| |
| From: Zhang Yi <yi.zhang@huawei.com> |
| |
| commit e5e7010e5444d923e4091cafff61d05f2d19cada upstream. |
| |
| After converting fs shrinkers to new scan/count API, we are no longer |
| pass zero nr_to_scan parameter to detect the number of objects to free, |
| just remove this check. |
