[LTP] FORK_OR_VFORK

[Stanislav Kholmanskikh <stanislav.kholmanskikh@oracle.com>]

Hello!

LTP employs FORK_OR_VFORK macro which is defined as:

#ifdef UCLINUX
#define FORK_OR_VFORK                   vfork
#define MAP_PRIVATE_EXCEPT_UCLINUX      0
#else
#define FORK_OR_VFORK                   fork
#define MAP_PRIVATE_EXCEPT_UCLINUX      MAP_PRIVATE
#endif

So, on UCLINUX it is a vfork call.

But many testcases use this macro and try to use functions other than 
exec() and _exit() inside a child.
Example - syscalls/setfsuid/setfsuid04.c.
And I suppose that because of that fact these testcases may fail on 
UCLINUX (or behave unexpectedly).

Is this situation left intentionally? Does somebody care about this 
issue? Or we simply ignore it.

I'm just curious. :)

Thanks.
