    Subject[PATCH 5.14 797/849] f2fs: include non-compressed blocks in compr_written_block
    Date
    From: Daeho Jeong <daehojeong@google.com>

    commit 09631cf3234d32156e7cae32275f5a4144c683c5 upstream.

    Need to include non-compressed blocks in compr_written_block to
    estimate average compression ratio more accurately.
