Subject: [PATCH v7 0/2] erofs-utils: support tail-packing inline compressed data
Date: Tue, 21 Dec 2021 17:43:19 +0800 [thread overview]
Message-ID: <20211221094321.108367-1-hsiangkao@linux.alibaba.com> (raw)
Hi folks,
This is a follow-up of previous v6 Yue Hu's patchset. It implements
tail-packing inline for compressed files. In particular, called
tail pcluster inline.
Here is some evaluation of Linux 5.10.87 source code (75368 inodes):
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) 345649152
Thanks,
Gao Xiang
