The code paths for Alt-SysRq-t are sprinkled with touch_nmi_watchdog in various places but not in this routine (or in the loop that utilizes this function). The patch has been tested for regression on large CPU+memory configuration (128 logical CPUs + 224 GB) and 1,2,4,16-CPU sockets with various memory sizes (1,2,4,6,20).
