It's pointless.  panic() will do a dump_stack().

sure.  The code looks rather miserable in an 80-col display.

there's also

WARNING: braces {} are not necessary for single statement blocks
#119: FILE: dyn_array.c:119:
+               if (da->init_work) {
+                       da->init_work(da);
+               }



and checkpatch should have detected the misplaced semicolon here:

+       for (daa = __per_cpu_dyn_array_start ; daa < __per_cpu_dyn_array_end; daa++) {

but didn't.
