[lc-checkins] CVS: linux/mm page_alloc.c,1.19,1.20

[Rodrigo S. de C. <rc...@us...>]

Update of /cvsroot/linuxcompressed/linux/mm
In directory usw-pr-cvs1:/tmp/cvs-serv12868/mm

Modified Files:
	page_alloc.c 
Log Message:
Bug fixes

o Fixed compilation error when compressed cache is disabled
o Fixed bug that would store pages with buffers even if the page cache
support were disabled
o Fixed bug that would not account the comp pages with zero fragments in
/proc/comp_cache_hist. They were displayed in the total column, but not in
the zero fragments column.
o Fixed bug in comp_cache_fix_watermarks() that would set
zone_num_comp_pages to a bogus value of num_comp_page. 

Other

o Added code to remove pages with buffers stored in the compressed
cache from LRU lists. These codes are within "#if 0" clauses.
o Allocate vswap table only when it is first used.
o Reduce compressed cache minimum size from 10 to 5%.
