test_lru_sanity5() fails when the number of online cpus
is fewer than the number of possible cpus. It can be
reproduced with qemu by using cmd args "--smp cpus=2,maxcpus=8".
The problem is the loop in test_lru_sanity5() is testing
'i' which is incorrect.
This patch:
1. Make sched_next_online() always return -1 if it cannot
find a next cpu to schedule the process.
2. In test_lru_sanity5(), the parent process does
sched_setaffinity() first (through sched_next_online())
and the forked process will inherit it according to
the 'man sched_setaffinity'.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
