Hi - I posted this on kernelnewbies and gregkh recommended I post here. I would appreciate any suggestions. I ran kselftest and it appears to have not finished due to errors from test_num & fw_userhelper: afustini@lappy486:~/dev/linux/lappy486/git/kernels/mainline$ sudo make kselftest <snip> == Testing sysctl behavior against /proc/sys/vm/swappiness == Writing test file ... ok Checking sysctl is not set to test value ... ok Writing sysctl from shell ... ok Resetting sysctl to original value ... ok Writing entire sysctl in single write ... ok Writing middle of sysctl after synchronized seek ... FAIL Writing beyond end of sysctl ...
