Subject: [PATCH v2 0/2] Btrfs: compression fixes
Date: Sat, 20 May 2017 19:49:51 +0300 [thread overview]
Message-ID: <20170520164953.7344-1-nefelim4ag@gmail.com> (raw)
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)
Timofey Titovets (2):
Btrfs: lzo.c pr_debug() deflate->lzo
Btrfs: compression must free at least PAGE_SIZE
fs/btrfs/lzo.c | 7 +++++--
fs/btrfs/zlib.c | 3 ++-
