/* which says: */
/* This patch adds support for the TFD_NONBLOCK flag to timerfd_create. The */
/* additional changes needed are minimal. 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> */

/* 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. */
