    f2fs: check filename length in recover_dentry · d96b1431
    Chao Yu authored
    In current flow, we will get Null return value of f2fs_find_entry in
    recover_dentry when name.len is bigger than F2FS_NAME_LEN, and then we
    still add this inode into its dir entry.
    To avoid this situation, we must check filename length before we use it.
    
    Another point is that we could remove the code of checking filename length
    In f2fs_find_entry, because f2fs_lookup will be called previously to ensure of
    validity of filename length.
    
    V2:
     o add WARN_ON() as Jaegeuk Kim suggested.
