    Subject[PATCH 5.17 0886/1126] f2fs: compress: fix to print raw data size in error path of lz4 decompression
    Date
    From: Chao Yu <chao@kernel.org>

    [ Upstream commit d284af43f703760e261b1601378a0c13a19d5f1f ]

    In lz4_decompress_pages(), if size of decompressed data is not equal to
    expected one, we should print the size rather than size of target buffer
    for decompressed data, fix it.
