+Subject: [PATCH] cyclictest: Fix threads being affined even when -a isn't set
+
+Using cyclictest without specifying affinity via -a, I was
+noticing a strange issue where the rt threads where not
+migrating when being blocked.
+
+After lots of debugging in the kernel, I found its actually an
+issue with cyclictest.
+
+When using -t there is no behavioral difference between specifying
+-a or not specifying -a.
+
+This can be confirmed by adding printf messages around the
+pthread_setaffinity_np() call in the threadtest function.
+
+Currently:
+
+root@localhost:~/rt-tests# ./cyclictest -t -a -q -D1
+Affining thread 0 to cpu: 0
+Affining thread 1 to cpu: 1
+Affining thread 2 to cpu: 2
+Affining thread 3 to cpu: 3
+Affining thread 4 to cpu: 4
+Affining thread 5 to cpu: 5
+Affining thread 7 to cpu: 7
+Affining thread 6 to cpu: 6

+..
+
+This issue seems to come from the logic in process_options():
+	/* if smp wasn't requested, test for numa automatically */
+	if (!smp) {
+		numa = numa_initialize();
+		if (setaffinity == AFFINITY_UNSPECIFIED)
+			setaffinity = AFFINITY_USEALL;
+        }
+
+Here, by setting setaffinity = AFFINITY_USEALL, we effectively
+pin each thread to its respective cpu, same as the "-a" option.
+
+This was most recently introduced in commit bdb8350f1b0b
+("Revert "cyclictest: Use affinity_mask for steering
+thread placement"").
+
+This seems erronious to me, so I wanted to share this patch
+which removes the overriding AFFINITY_UNSPECIFIED with
+AFFINITY_USEALL by default. Also, some additional tweaks to
+preserve the existing numa allocation affinity.
+
+With this patch, we no longer call pthread_setaffinity_np() in the
+"./cyclictest -t -q -D1"  case.
