    Subject[PATCH AUTOSEL 5.9 106/147] f2fs: fix to set SBI_NEED_FSCK flag for inconsistent inode
    Date
    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.
