The main reason is that write_cache_pages() doesn't (and can't) check PG_fscache (btrfs uses PG_private_2 for other purposes). NFS, 9p and ceph, for the moment, don't cache files that are open for writing, but I'm intending to change that at some point. The intention is to unify the writepages code for at least 9p, afs, ceph and cifs in netfslib in the future. David
