[PATCH v3 0/2] Btrfs: compression fixes

[Timofey Titovets <nefelim4ag@gmail.com>]

First patch: fix copy paste typo in debug message in lzo.c, lzo is not deflate

Second patch: force btrfs to not store data as compressed, if compression will not
free at least one PAGE_SIZE, because it's useless in term of storage 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

Timofey Titovets (2):
  Btrfs: lzo.c pr_debug() deflate->lzo
  Btrfs: compression must free at least PAGE_SIZE
