Title:
  bits/fcntl.h does not define AT_EMPTY_PATH

Status in “eglibc” package in Ubuntu:
  Fix Released
Status in “eglibc” source package in Precise:
  Fix Released

Bug description:
  SRU Justification:

  [Impact]
  A fix is needed for qemu-kvm to compile the virtio-9p-handle.c file.

  [Development Fix]
  This is fixed in quantal.

  [Stable Fix]
  A fix can be backported from quantal into precise.

  [Test Case]
  Try to compile the virtio-9p-handle.c file in qemu-kvm.

  [Regression Potential]
  This patch adds AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, AT_EMPTY_PATH, and AT_EACCESS to the proper fcntl.h files.

  This bug is not upstream, and the define is too new to appear in
  debian.  Upstream, AT_EMPTY_PATH is defined in io/fcntl.h.  In debian,
  debian/patches/any/submitted-bits-fcntl_h-at.diff moves the *AT
  defines into the per-arch bits/fcntl.h files.  The ubuntu-specific
  merge of newer upstream updated the patch doing so to remove the
  AT_EMPTY_PATH with the rest of that blcok from io/fcntl.c, but does
  not add it to the bits/fcntl.h files.

  This is needed for qemu-kvm to compile the virtio-9p-handle.c file.

  A debdiff is attached which adds the definition.
