4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trondmy@xxxxxxxxx>
commit 2a534a7473bf4e7f1c12805113f80c795fc8e89a upstream.
Now that the value of 'ino' can be NULL or an ERR_PTR(), we need to
change the test in the tracepoint.
Fixes: ce5624f7e6675 ("NFSv4: Return NFS4ERR_DELAY when a layout fails...")
