| Subject: f2fs: fix to set SBI_NEED_FSCK flag for inconsistent inode |
| |
| From: Chao Yu <yuchao0@huawei.com> |
| |
| [ Upstream commit d662fad143c0470ad7f46ea7b02da539f613d7d7 ] |
| |
| If compressed inode has inconsistent fields on i_compress_algorithm, |
| i_compr_blocks and i_log_cluster_size, we missed to set SBI_NEED_FSCK |
| to notice fsck to repair the inode, fix it. |
