NFSv4.2: llseek(SEEK_HOLE) and llseek(SEEK_DATA) don't require data sync
We want to ensure that we write the cached data to the server, but don't require it be synced to disk. If the server reboots, we will get a stateid error, which will cause us to retry anyway. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
