+Subject: [PATCH] memfd: fix configure test
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Recent glibc added memfd_create in sys/mman.h.  This conflicts with
+the definition in util/memfd.c:
+
+    /builddir/build/BUILD/qemu-2.11.0-rc1/util/memfd.c:40:12: error: static declaration of memfd_create follows non-static declaration
+
+Fix the configure test, and remove the sys/memfd.h inclusion since the
+file actually does not exist---it is a typo in the memfd_create(2) man
+page.
