problem where a deleted node points to another deleted node, and we
only have a hazard pointer for the first node.

old method left a race condition, since hazard_scan stops at the first

7660467f8e Refactor page implementation to use multiple include trick (so the backing representation can be changed). 
Also, fix apparent bug in stasis_page_fixed_set_record_type().

Otherwise, this change should not make any semantic changes.

b126b45bcc Improve sequential write performance of buffer manager. 
This patch adds support for "asyncForce" which forces all pages to disk that
were dirtied before the *previous* call call to asyncForce.  This method
only applies to dirty pages in the Linux file cache (not in the Stasis buffer
pool), and is used by new writeback logic that bounds the amount of such
backlog that exists at any given time.

This patch also changes writeback behavior; the dirty page table now sorts
pages by pageid instead of LSN when it is invoked by writeback.  When it is
invoked by log truncation, it still sorts by LSN.

7f332f85cc fix deadlock in filePool logger. The deadlock was due to pages being evicted before Tupdate() released the log entry for writeback. Now, we track another timestamp, so that Tupdate() starts with something analogous to a writelock, and downgrades it to a readlock before pinning pages, and invoking callbacks 2011-07-15 17:37:50 +00:00
