Subject: [PATCH v3 0/5] erofs: support tail-packing inline compressed data
Date: Sat, 25 Dec 2021 15:06:21 +0800 [thread overview]
Message-ID: <20211225070626.74080-1-hsiangkao@linux.alibaba.com> (raw)
Hi folks,
v2: https://lore.kernel.org/r/20211215094449.15162-1-huyue2@yulong.com
mkfs v8: https://lore.kernel.org/r/20211224012316.42929-1-hsiangkao@linux.alibaba.com
This is the 3rd version of tail-packing inline compressed data feature.
It tries to inline the tail pcluster right after the inode metadata to
save data I/O and storage space.
Take Linux 5.10.87 source code as an example:
linux-5.10.87 (erofs, uncompressed) 972570624
linux-5.10.87 (erofs, lz4hc,9 4k tailpacking) 391696384
linux-5.10.87 (erofs, lz4hc,9 8k tailpacking) 368807936
linux-5.10.87 (erofs, lz4hc,9 16k tailpacking) 345649152
linux-5.10.87 (erofs, lz4hc,9 4k vanilla) 416079872
linux-5.10.87 (erofs, lz4hc,9 8k vanilla) 395493376
linux-5.10.87 (erofs, lz4hc,9 16k vanilla) 383213568
Thanks,
Gao Xiang
changes since v2:
- properly split patches;
- some code cleanup.
