-    PR22005: Fix @min() and @max() extractor functions.
-    
-    Commit 26382d613f4d26 introduced a regression in @min()
-    and @max() extractor functions.  Example:
-    
-    $ stap -e 'global n probe oneshot {n<<<12 n<<<34 println(@max(n))}'
-    12
-    $
-    
-    This commit fixes the regression and adds a testcase.

+    rhbz1504009: let dtrace -G -o /dev/null run, as in autoconf
+    
+    commit c245153ca193c471a8c broke the ability of dtrace to be tested in
+    autoconf "-G -o /dev/null" usage, because its output file name was too
+    simple a function of the input name, and normal users can't write to
+    /dev/null.dtrace-temp.c .  Now we back down to mkstemp, like before,
+    upon a failure of the simple concatenated name.

+    BZ1527809 - Fix detaching from modules using SIGQUIT.
+    
+    * staprun/mainloop.c: Put a "/* NOTREACHED */" comment after all calls to
+      cleanup_and_exit() to remind the reader that cleanup_and_exit() doesn't
+      return.
+      (stp_main_loop): If we've got a pending interrupt,
+      but 'load_only' is set, just detach instead of sending STP_EXIT to
+      the module. Otherwise using SIGQUIT to detach fails and unloads the
+      module.
+    * staprun/monitor.c: Put a "/* NOTREACHED */" comment after all calls to
+      cleanup_and_exit() to remind the reader that cleanup_and_exit() doesn't
+      return.
+    * testsuite/systemtap.base/attach_detach.exp: New test.
