| Subject: f2fs: report delalloc reserve as non-free in statfs for project quota |
| |
| From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> |
| |
| [ Upstream commit baaa7ebf25c78c5cb712fac16b7f549100beddd3 ] |
| |
| This reserved space isn't committed yet but cannot be used for |
| allocations. For userspace it has no difference from used space. |
| |
| See the same fix in ext4 commit f06925c73942 ("ext4: report delalloc |
| reserve as non-free in statfs for project quota"). |
| |
| Fixes: ddc34e328d06 ("f2fs: introduce f2fs_statfs_project") |
