glibc/dirent/tst-fdopendir2.c
Ulrich Drepper a4f1763067 * sysdeps/unix/fdopendir.c (fdopendir): If O_DIRECTORY is
available, avoid stat call, use fcntl result to determine whether
	descriptor is for a directory or not.
	* dirent/Makefile (tests): Add tst-fdopendir2.
	* dirent/tst-fdopendir2.c: New file.
