buf0lru.c, buf0flu.c, buf0buf.c, buf0lru.h:
Search first only 10 % of the LRU list for a replaceable block before doing an LRU flush; enable again flushing of close pages also in a flush list (checkpointing) flush
trx0trx.c:
Add forgotten return value (it was not used anywhere, fortunately)
ha_innodb.h, mysql_priv.h:
Move declaration of srv_buf_pool_max_modified_pct to ha_innodb.h and enclose it to denote it is a C variable, not C++
