David Howells 0770bd4187 afs: Skip truncation on the server of data we haven't written yet ... Don't send a truncation RPC to the server if we're only shortening data that's in the pagecache and is beyond the server's EOF. Also don't automatically force writeback on setattr, but do wait to store RPCs that are in the region to be removed on a shortening truncation.
