| /* says: */ |
| /* This patch introduces the new syscall inotify_init1 (note: the 1 stands for*/ |
| /* the one parameter the syscall takes, as opposed to no parameter before). */ |
| /* The values accepted for this parameter are function-specific and defined in*/ |
| /* the inotify.h header. Here the values must match the O_* flags, though. */ |
| /* In this patch CLOEXEC support is introduced. */ |
| /* 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_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 */ |
