I assume the change to dev_loss_tmo is simply a preference issue. Like
Netapp, they don't want their devices to get auto-removed when they go
down. I also assume that in their internal testing, they hit cases where
5 seconds wasn't enough time to wait for some transient issue with the
array to resolve. At any rate, I'm simply passing along their request,
which seems like a perfectly reasonable one to me.
