IJ54629: MMRESTOREFS FAILS TO RECREATE SOCKET FILE ON AIX.

APAR status

• Closed as program error.

Error description

• mmrestorefs recreates all files and directories that were
  deleted after the snapshot was taken.If the deleted file is a
  special file, mmrestorefs uses mknod() system call to create the
  file.But mknod() cannot create a socket file on AIX. Hence, if
  socket files were deleted after the snapshot was
  taken,mmrestorefs on AIX will fail during re-creating the socket
  file.
