It also more portable and easier to debug if the cache is in user space. My preference is to keep the kernel module as simple as we can.

hey,

that's an open topic i think. keep in mind that we're actively trying to avoid the kernel in some systems (e.g. BG/*)...

Hi guys,
Is this the general direction for caching in PVFS2? A user-space cache
which is timeout-based rather than completely coherent may as well be kept
inside the kernel module, no? :)
Sorry if I am stirring up a hornet's nest or if this was discussed
before...
Thanks,
Murali
