From 57940b435cd1dab6529babcda095c47ecee8a8e9 Mon Sep 17 00:00:00 2001 From: Ryan Moeller Date: Mon, 10 Feb 2020 16:11:30 -0500 Subject: Share some code for spa deadman tunables We need to do the same thing to update all spas on any OS for these tunables, so let's share the code. While here let's match the types of the literals initializing the variables with the type of the variable.
