/* Description: This Program tests the new system call introduced in 2.6.27. */
/* Ulrich´s comment as in: */
/* http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b087498eb5605673b0f260a7620d91818cd72304 */
/* says: */
/* This patch adds the new eventfd2 syscall. It extends the old eventfd */
/* syscall by one parameter which is meant to hold a flag value. In this */
/* patch the only flag support is EFD_CLOEXEC which causes the close-on-exec */
/* flag for the returned file descriptor to be set. A new name EFD_CLOEXEC is */
/* introduced which in this implementation must have the same value as */
/* O_CLOEXEC. The following test must be adjusted for architectures other than*/
/* x86 and x86-64 and in case the syscall numbers changed. */
/* */
/* Usage: <for command-line> */
/* eventfd2_01 [-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. */
/* */
/* Total Tests: 1 */

/* Test Name: eventfd2_01 */
