Btw, one issue with using direct I/O is that need to synchronize with
page cache access from the server itself. For pNFS we can do that as
we track outstanding layouts. Without layouts it will be more work
as we'll need a different data structure tracking grant for bypassing
the server. Or just piggy back on layouts anyway as that's what they
are doing.
