[PATCH v2 1/8] staging: erofs: add compacted ondisk compression indexes

2019-06-20 Thread Gao Xiang
This patch introduces new compacted compression indexes. In contract to legacy compression indexes that each 4k logical cluster has an 8-byte index, compacted ondisk compression indexes will have amortized 2 bytes for each 4k logical cluster (compacted 2B) amortized 4 bytes for each 4k lo
