Err, no. First, you assume that the Linux cache can be arbitrarily large
(or at least that enough memory is available to cache reasonable working
sets); second, cachefs is persistent across reboots, which the Linux buffer
cache cannot be.
There's also the fact that AFS, DFS, and Coda all have a cachefs-equivalent
built into them: reads and writes are redirected to the local vice cache,
which is synced on close. This isn't merely because it's somehow easier than
using the OS buffer cache.
