+Subject: [PATCH] rt-migrate: Use int instead of pthread_t for thread IDs
+
+pthread_t is opaque, but create_fifo_thread() returns integer therefore
+on musl where thread_t is not integer, this fails to compile e.g.
+
+| rt-migrate.c:450:14: error: incompatible integer to pointer conversion assigning to 'pthread_t' (aka 'struct __pthread *') from 'int' [-Wint-conversion]
+|                 threads[i] = create_fifo_thread(start_task, (void *)i,
+|                            ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Align the types used to fix the problems.
