+- Update to release 5.3.0
+  * Added the thread.idle mallctl which hints that the calling
+    thread will be idle for a nontrivial period of time.
+  * Allow small size classes to be the maximum size class to
+    cache in the thread-specific cache, through the
+    opt.[lg_]tcache_max option.
+  * Make the behavior of realloc(ptr, 0) configurable with
+    opt.zero_realloc.
+  * Support C++17 over-aligned allocation.
+  * Add the thread.peak mallctl for approximate per-thread peak
+    memory tracking.
+  * Add high resolution timestamp support for profiling.
+- Drop use-volatile-to-workaround-buffer-overflow-false-pos.patch
+  (merged)

-Subject: [PATCH] Use volatile to workaround buffer overflow false positives.

-In test/integration/rallocx, full usable size is checked which may confuse
-overflow detection.
