commit f4a2740a69d34b3ab0a7ecc7d4785b4b6b68e7cf
Author: Joseph Myers <joseph@codesourcery.com>

    Remove linux/fanotify.h configure test.
    
    Now we require Linux 3.2 or later kernel headers everywhere, the
    configure test for <linux/fanotify.h> is obsolete; this patch removes
    it.
    
    Tested for x86_64.
    
    	* sysdeps/unix/sysv/linux/configure.ac (linux/fanotify.h): Do not
    	test for header.
    	* sysdeps/unix/sysv/linux/configure: Regenerated.
    	* config.h.in (HAVE_LINUX_FANOTIFY_H): Remove #undef.
    	* sysdeps/unix/sysv/linux/tst-fanotify.c [!HAVE_LINUX_FANOTIFY_H]:
    	Remove conditional code.
    	[HAVE_LINUX_FANOTIFY_H]: Make code unconditional.
