Update of /cvsroot/linuxcompressed/linux/mm
In directory usw-pr-cvs1:/tmp/cvs-serv6713/mm

Modified Files:
	filemap.c 
Log Message:
Bug fixes
o We were only accounting writeout statistics if the writepage()
returned one, but returning zero doesn't mean it has not been written
tough (swap_writepage() always returns zero). So, it ended up that we
didn't account any writeout page because most writepage() functions
return zero. Now we account every written page, no matter the return
value.

o Fixed CompCache bit assignment, so now we don't have to search
compressed cache for every page that gets compressed. Given that, a
PageCompCache(page) does not mean it has a fragment in compressed
cache, but a !PageCompCache(page) surely doesn't have a fragment. That
improves performance.

Cleanups
o Don't printk initial compressed cache size, only the maximum size
o comp_data defined as static in proc.c
