We ended up with two [Description] sections here, I guess that we should
remove the second occurence of '[Description]' here.

Why don't we change the code so that the setup function returns the
filedescriptor? That would make the code much more straightforward.

I'm pretty sure the umask() here is useless.


Otherwise it looks good.

Hi, Cyril,

I will modify it based on your comments. In addition, changes for close08 will be incorporated into this case.

Thanks for your review.

- *
- * 	Setup:
- * 	  Setup signal handling.
- *	  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)
- *		Log the errno and Issue a FAIL message.
- *	  Otherwise, Issue a PASS message.
- *
- * 	Cleanup:
- * 	  Print errno log and/or timing stats if options given

[LTP] [PATCH 3/3 v2] syscalls/close: Convert close08 to the new API

[Cyril Hrubis]

Hi!
Isn't this test just the same as close01.c?

I think that we can just remove close08.c since it does not add any more
coverage over close01.

Also we can add all kind of other file descriptor to the close01.c test
as well. We should add at least a few different socket fds there as well.
