fault-injection: add CPU notifier error injection module
I used this module to test the series of modification to the cpu notifiers code. Example1: inject CPU offline error (-1 == -EPERM) # modprobe cpu-notifier-error-inject cpu_down_prepare_error=-1 # echo 0 > /sys/devices/system/cpu/cpu1/online bash: echo: write error: Operation not permitted Example2: inject CPU online error (-2 == -ENOENT) # modprobe cpu-notifier-error-inject cpu_up_prepare_error=-2 # echo 1 > /sys/devices/system/cpu/cpu1/online bash: echo: write error: No such file or directory [akpm@linux-foundation.org: fix Kconfig help text] Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
