/* File: inotify_init1_02.c */

/* 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=510df2dd482496083e1c3b1a8c9b6afd5fa4c7d7 */
/* which says: */
/* This patch adds non-blocking support for inotify_init1. 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> */
/* inotify_init1_02 [-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 */
