Fix the QEMU memfd compile error:
tools/qemu-xen/util/memfd.c:40:12: error: static declaration of 'memfd_create' follows non-static declaration
static int memfd_create(const char *name, unsigned int flags)
^~~~~~~~~~~~
that has been introduced since the Glibc 2.27 upgrade.
This just involves porting the upstream QEMU patch to the Xen QEMU tree.
This fixes:

Subject: [PATCH] memfd: fix configure test

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.
