Do we need to order writes, or do we need to merely know when a write
has completed, and let the FS order the writes?
For reiserfs it is enough to know that the write has completed, where
completed may be NVRAM on the RAID controller, I don't need to know.
Precisely. A journalling file system should be happy if we know when the write
has been committed and if we know that no write request will remain outstanding
indefinitely so that we don't need an infinite journal.
