I have seen tail_alloc() being used at a lot of places in tests. For
example, in ioctl_hdio.c, and epoll_pwait.c.
File tests.h gives information about what it does but I don't
understand the motive and use of allocating memory in such a manner.
What is the purpose of it? How is it helpful in testing?
Another query is about error_msg.c file:
#define perror_msg_and_fail perror_msg_and_fail
#define error_msg_and_fail error_msg_and_fail
What is the reason for doing this?
