Merge Revision revid:inaam.rana@oracle.com-20100820163904-vdwn6uflh3ymvwau from MySQL InnoDB
Original revid:inaam.rana@oracle.com-20100820163904-vdwn6uflh3ymvwau
Original Authors: Inaam Rana <inaam.rana@oracle.com>
Original commit message:
When flushing from LRU we try to keep a certain number of pages over
and above the general requirement free. We call them
BUF_FLUSH_EXTRA_MARGIN. With multiple buffer pools we may end up keeping
this amount of pages for each buffer pool. This patch, diagnosed and fixed
by Michael, throttles flushing in such cases.
