Could you not create a raw device and install a filesystem on it for
your data? Access to the raw device would bypass the Linux cache.
Your application would need to be specifically coded for that kind of
access, and know how to manage raw blocks.
Dave: you can't turn the Linux cache
Folks, does anyone know how to build a Linux 2.4.x kernel that has Linux
file caching disabled? I want to disable Linux's file caching and let
CP's minidisk caching functions do it instead, and to reduce the virtual
storage requirements for the guest.
TIA.

I think there are a few options other than the intuitive ones.
I saw in some lab experiments some trick where you can mount a
filesystem Synchrounous or something so that Linux does not
buffer output. Not sure if this affects reads.
There is also the new cooperative memory management where
