Hi cepher, I noticed that when PG worker is processing the op, it may acquire obc->ondisk_read_lock or obc->ondisk_write_lock. it's used to protect concurrent read and write to same object. But to my understanding, the PG lock is held while worker is processing op which already prevent concurrent access for the same object. Does that mean those locks are not actually needed?
