This avoids the costly rescan of the LRU list. (Bug #35077, Issue #449) At most one buffer-fix will be active at a time, affecting two blocks: the buf_page_t and the compressed page frame. This should not block the memory defragmentation in buf0buddy.c too much. In fact, it may avoid unnecessary copying if also prev_bpage belongs to the tablespace that is being invalidated. rb://240
