This series contains random fixes and cleanups to free page isolation in compaction. This is based on another compact series[1]. More details can be found in respective patches. This patch (of 4): We will set skip to page block of block_start_pfn, it's more reasonable to set compact_cached_free_pfn to page block before the block_start_pfn.
