Update of /cvsroot/linuxcompressed/linux/include/linux
In directory usw-pr-cvs1:/tmp/cvs-serv27511/include/linux
Modified Files:
comp_cache.h
Log Message:
Bug fix:
o Fixed a bug that would freeze a system where the compressed cache is not
enabled. The return value of compress_clean_page() was wrong, making the
shrink_cache() function to not free any page. The return value was fixed,
but to avoid overheads when compressed cache is disabled, that part of the
code in vmscan.c now also has "#ifdef CONFIG_COMP_CACHE".
