Can you get some tracing?

echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_read/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_rreq/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_sreq/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_failure/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_write_iter/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_write/enable

Thanks,
David
