Here you go.  First batch of tests.  Please review - and test:-)

commit fff886ec7ee53aa266a12d9dbb2825952fa1adb9
Author: David Howells <dhowells@xxxxxxxxxx>
Date:   Mon Mar 27 21:42:32 2017 +0100

    Add initial batch of statx() LTP tests
    
    Add an initial batch of statx() tests for LTP, deriving them from all of
    the stat(), fstat() and lstat() tests.
    
    Note that since statx() is not yet implemented in glibc, a header file is
    added to provide the missing system call bits.

+ * Test Name: statx03
+ *
+ * Test Description:
+ *   Verify that,
+ *   1) statx(2) returns -1 and sets errno to EACCES if search permission is
+ *      denied on a component of the path prefix.
+ *   2) statx(2) returns -1 and sets errno to ENOENT if the specified file
+ *	does not exists or empty string.
+ *   3) statx(2) returns -1 and sets errno to EFAULT if pathname points
+ *	outside user's accessible address space.
+ *   4) statx(2) returns -1 and sets errno to ENAMETOOLONG if the pathname
+ *	component is too long.
+ *   5) statx(2) returns -1 and sets errno to ENOTDIR if the directory
+ *	component in pathname is not a directory.
+ *
+ * Expected Result:
+ *  statx() should fail with return value -1 and set expected errno.
+ *
+ * Algorithm:
+ *  Setup:
+ *   Setup signal handling.
+ *   Create temporary directory.
+ *   Pause for SIGUSR1 if option specified.
+ *
+ *  Test:
+ *   Loop if the proper options are given.
+ *   Execute system call
+ *   Check return code, if system call failed (return=-1)
+ *   	if errno set == expected errno
+ *   		Issue sys call fails with expected return value and errno.
+ *   	Otherwise,
+ *		Issue sys call fails with unexpected errno.
+ *   Otherwise,
+ *	Issue sys call returns unexpected value.
+ *
+ *  Cleanup:
+ *   Print errno log and/or timing stats if options given
+ *   Delete the temporary directory(s)/file(s) created.
+ *
+ * Usage:  <for command-line>
+ *  statx03 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
+ *	where,  -c n : Run n copies concurrently.
+ *		-e   : Turn on errno logging.
+ *		-i n : Execute test n times.
+ *		-I x : Execute test for x seconds.
+ *		-P x : Pause for x seconds between iterations.
+ *		-t   : Turn on syscall timing.
+ *
+ * Restrictions:
