First patch: Fix copy paste typo in debug message for lzo.c, lzo is not deflate
Second patch: Force btrfs to not store data as compressed, if compression will not free at least one sector size, because it's useless in term of saving storage space and reading data from disk, as a result productivity suffers. Changes since v1: - Merge patches for zlib and lzo in one - Sync check logic for zlib and lzo - Check profit after all data are compressed (not while compressing) Changes since v2: - Fix comparassion logic, it's enough if: compressed size + PAGE_SIZE not bigger then input data size Changes since v3: - Use btrfs sector size directly instead of assume that PAGE_SIZE == sectorsize Timofey Titovets (2): Btrfs: lzo.c pr_debug() deflate->lzo Btrfs: compression must free at least one sector size fs/btrfs/lzo.c | 11 +++++++++-- fs/btrfs/zlib.c | 7 ++++++- 2 files changed, 15 insertions(+), 3 deletions(-) -- 2.13.0 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
