Update of /cvsroot/linuxcompressed/linux/include/linux
In directory usw-pr-cvs1:/tmp/cvs-serv23908/include/linux
Modified Files:
comp_cache.h swap.h
Log Message:
- Clean pages support in compressed cache is improved even more.
- Clean and dirty pages are only removed from the compressed cache
when writeout_fragments() is called or the program exits.
- removed an obsolete code for CONFIG_COMP_SWAP
- improved writeout_fragments(), which will try to free fragments even
if we can't perform IO. In this case, we will free only clean
fragments.
