Change subject: [log_block_manager] Write lock for deletion ...................................................................... [log_block_manager] Write lock for deletion Both removing blocks and compacting metadata manipulates the live_blocks_ value and file content. This way it can happen that on thread A live_blocks_ is updated, on thread B metadata is compacted and live_blocks_ value is overwritten, then thread A writes deletion records in the metadata file. This way it creates inconsistency between file content and live_blocks_ value, which leads to incorrect behaviour to skip compaction later. This fix makes sure that CompactMetadata and deletion can not overlap each other.
