sdong ecb1ffa2a8 Buffer info logs when picking compactions and write them out after releasing the mutex ... Summary: Now while the background thread is picking compactions, it writes out multiple info_logs, especially for universal compaction, which introduces a chance of waiting log writing in mutex, which is bad. To remove this risk, write all those info logs to a buffer and flush it after releasing the mutex. Test Plan: make all check check the log lines while running some tests that trigger compactions.
