From: Shuang Qiu <shuang.qiu@oracle.com>

It does not unmap the mapped address region,so we sometimes still get
such
warning when cleanup with nfs as TMPDIR although the file descriptor is
closed:
0  TWARN  :  tst_rmdir: rmobj(/mnt/nfsv3/ltp-MOeIFH7102/vma4FwRqb)
failed:
unlink(/mnt/nfsv3/ltp-MOeIFH7102/vma4FwRqb/.nfs000000000110cb3600000001)
failed; errno=16: Device or resource busy
