-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.

-Cc: Marc-André Lureau <marcandre.lureau@redhat.com>
