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.
