Subject: [PATCH] Branch HEAD Disable client page cache checksumming by
 default. This does not affect the wire checksumming, and only adds a lot of
 CPU overhead that is mostly useful only for debugging rare client memory
 corruption vs. the more common network transfer corruption. It can be enabled
 at runtime via "echo 1 > $LPROC/llite/*/checksum_pages". b=13579 i=scjody
