Sears Russell	0154f7d29d	IMPORTANT API CHANGE: stasis_dirty_page_table_flush_range() no longer force writes to disk. You now need to call forcePageRange() after flush page range returns. ... This commit should significantly improve sequential write thoughput. I found a segfault bug this morning, but cannot reproduce. Could be a heisenbug, or could have been a hardware fault (gojira repeatedly kernel paniced, then both problems went away...)	2009-08-13 05:53:48 +00:00
Sears Russell	0cc65aefaf	Remove LRU-ordered writeback. Instead, writeback pages sequentially once some fraction of the page file is dirty. Also. further simplifies writeback code.	2009-08-11 17:23:43 +00:00
Sears Russell	a0f9a7bc81	Cleaned up page locking + a harmless memory bug. Add missing locks to page writeback.	2009-08-08 07:59:19 +00:00
Sears Russell	907a24b68e	dirty page table flush was pinning pages, then asserting they were not pinned; updated page writeback api to allow correct usage	2009-08-08 01:43:03 +00:00
Sears Russell	c92ee87c32	improved behavior for sequential I/O performance, fixed races during writeback	2009-08-07 18:27:52 +00:00
Sears Russell	b44f8b17b3	Add getCachedPage() call. This allows dirtyPageTable to write back pages with out accidentally reading them back in from disk with loadPage(). This should improve performance and allow loadPageOfType() to be used safely.	2009-07-14 07:46:47 +00:00
Sears Russell	7db06197ca	refactored truncation + dirty page table, fixed doxygen warnings.	2009-05-20 21:23:51 +00:00
