Update of /cvsroot/linuxcompressed/linux/include/linux
In directory usw-pr-cvs1:/tmp/cvs-serv29510/include/linux
Modified Files:
comp_cache.h
Added Files:
lzoconf.h minilzo.h
Log Message:
- Support for LZO compression algorithm is back
echo 2 > /proc/sys/vm/comp_cache/algorithm
- Now there is a /proc/comp_cache_hist that shows the free space histogram.
That histogram now also displays how many fragments the pages have, so you
have a better picture of what's going on in the compressed cache.
