nice addition, thanks!

One nitpick and one general question.

Please don't do function calls in if expressions:

if ((val = SMB_VFS_FCNTL(fsp, F_GETFL, 0)) == -1) {
    return -1;
}

Instead:

val = SMB_VFS_FCNTL(fsp, F_GETFL, 0);
if (val == -1) {
    return -1;
}

Then, I wonder why you make a copy of va_args in the time_audit and
full_audit VFS modules before calling the NEXT function. Can't we just
pass the va_list on to the NEXT function?
