Update of /cvsroot/linuxcompressed/linux/mm/comp_cache
In directory usw-pr-cvs1:/tmp/cvs-serv5957/mm/comp_cache
Modified Files:
swapin.c
Log Message:
- Fixed compilation error in buffer.c when compiling it without compressed
cache.
- Fixed oops caused when running fillmem due to a null pointer
- Fixed major/minor faults for compressed cache. Now we have correct data
about when we actually had to perform IO to service a page fault.
- Improved support for clean pages. Now the clean page is compressed and
right away freed in shrink_cache().
- When a pte in do_no_page() has write access to the page, it's already set
as dirty. So, in the same way done in do_swap_page(), we already remove the
its fragment from compressed cache since it will need to be compressed again
anyway.
