This patch extracts page buffer pooling and the simple
least-recently-used strategy from clog.c into slru.c. It doesn'tchange any visible behaviour and passes all regression tests plus aTruncateCLOG test done manually.Apart from refactoring I made a little change to SlruRecentlyUsed,formerly ClogRecentlyUsed: It now skips incrementing lru_counts, ifslotno is already the LRU slot, thus saving a few CPU cycles. To makethis work, lru_counts are initialised to 1 in SimpleLruInit.SimpleLru will be used by pg_subtrans (part of the nested transactionsproject), so the main purpose of this patch is to avoid future codeduplication.Manfred Koizar
