VLE was an old informal name of fixed-sized output compression which came from published ATC'19 paper [1]. Drop those old annotations since erofs can handle all encoded clusters in block-aligned basis, which is wider than fixed-sized output compression after larger clustersize feature is fully implemented. Unaligned encoding won't be considered in EROFS since it's not friendly to inplace I/O and perhaps decompression inplace. a) Fixed-sized output compression with 16KB pcluster: ___________________________________ |xxxxxxxx|xxxxxxxx|xxxxxxxx|xxxxxxxx| |___ 0___|___ 1___|___ 2___|___ 3___| physical blocks b) Block-aligned fixed-sized input compression with 16KB pcluster: ___________________________________ |xxxxxxxx|xxxxxxxx|xxxxxxxx|xxx00000| |___ 0___|___ 1___|___ 2___|___ 3___| physical blocks c) Block-unaligned fixed-sized input compression with 16KB compression unit: ____________________________________________ |..xxxxxx|xxxxxxxx|xxxxxxxx|xxxxxxxx|x.......| |___ 0___|___ 1___|___ 2___|___ 3___|___ 4___| physical blocks Refine better names for those as well.
