> Just catch any OSError?

If possible, I would prefer to not retry O_TMPFILE each time if the kernel version does not support the flag.

Pseudo-code:
--
if o_tmpfile_supported:
   try:
      fd = os.open(dir, os.O_TMPFILE | ...)
   except IsADirectoryError:
      # Linux kernel older than 3.11 ignores O_TMPFILE flag
      o_tmpfile_supported = False
   except OSError:
      # the filesystem doesn't support O_TMPFILE
      pass
   else:
      return io.open(fd, ...)
   # fallback to unsafe but portable implementation

# current code generating a name and using unlink
