Public bug reported: [Summary] ubuntu_ltp: fs testsuite causing tainted kernel
[Steps to reproduce] on the dut: 1. git clone -b sru https://git.launchpad.net/~canonical-kernel-team/+git/ltp 2. sed -i /ntfs/d lib/tst_supported_fs_types.c 3. make autotools 4. ./configure 5. make -j8 6. make install 7. echo "read_all_sys read_all -d /sys -q -r 3" > /tmp/target 8. sudo su 9. /opt/ltp/runltp -f /tmp/target -q -C /dev/null -l /dev/null -T /dev/null [Expected result] should not cause any error or warning from kernel perspective stdout ------ [ 1910.735509] ICMPv6: process `proc01' is using deprecated sysctl (syscall) net.ipv6.neigh.default.base_reachable_time - use
