Comment 11 for bug 1469214

I re-ran this today with the following script as a non-root user:

#!/bin/bash
tests="affinity aio bigheap brk bsearch cache chdir chmod clock context cpu crypt dentry dir dup epoll eventfd fstat fallocate fault fifo flock fork futex get getrandom hdd hsearch inotify io itimer kcmp kill lease link lockf longjmp lsearch malloc matrix memcpy memfd mincore mlock mmap mmapmany mremap msg mq nice null open pipe poll procfs pthread qsort readahead rename rlimit seek sem sem-sysv sendfile shm-sysv sigfd sigfpe sigq sigsegv sock splice stack str switch symlink sysinfo sysfs tee timer timerfd tsearch udp udp-flood urandom utime vecmath vfork vm vm-rw vm-splice wcs wait yield xattr zero zombie"

for t in $tests
do
        echo $t
 echo $t | sudo tee /dev/kmsg
        ./stress-ng --$t 0 -v -t 60
done

and hit this issue:
