Subject: [PATCH 0/3] Btrfs: compression fixes
Date: Fri, 19 May 2017 16:38:32 +0300 [thread overview]
Message-ID: <20170519133835.27843-1-nefelim4ag@gmail.com> (raw)
First patch fix copy paste typo in debug message in lzo.c, lzo is not deflate
Second and third patches force btrfs not compress data if compression will not free at least one PAGE_SIZE
Because it's useless in term of storage and read data from disk, as a result productivity suffers
Timofey Titovets (3):
Btrfs: lzo.c pr_debug() deflate->lzo
Btrfs: lzo compression must free at least PAGE_SIZE
Btrfs: zlib compression must free at least PAGE_SIZE
