Hi, this patch enhanced the run_kselftest.sh to make the tests individually selectable. I'm not sure the if I could add the reuslt in the patch commit, as the log is too long. So I just put the result to the cover-letter:

Note: I use `tr -s "/-" "_"` to cover the path name in tests to function name. e.g. networking/timestamping -> networking_timestamping. I'm not sure if it's legal in Makefile.

Before the patch:

]# ./kselftest_install.sh /tmp/kselftests ]# cat /tmp/kselftests/run_kselftest.sh #!/bin/sh BASE_DIR=$(realpath $(dirname $0)) cd $BASE_DIR . ./kselftest/runner.sh ROOT=$PWD if [ "$1" = "--summary" ]; then logfile=$BASE_DIR/output.log cat /dev/null > $logfile fi [ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg cd android run_many \ "run.sh" cd $ROOT ...<snip>... [ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg cd zram run_many \ "zram.sh" cd $ROOT

After the patch: ]# ./kselftest_install.sh /tmp/kselftests ]# cat /tmp/kselftests/run_kselftest.sh #!/bin/sh BASE_DIR=$(realpath $(dirname $0)) . ./kselftest/runner.sh TESTS="android ...<snip>... zram"

run_android() { [ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg cd android run_many \ "run.sh" cd $ROOT }

...<snip>...

run_zram() { [ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg cd zram run_many \ "zram.sh" cd $ROOT }

usage() { cat <<EOF usage: ${0##*/} OPTS -s | --summary Only print summary info and put detailed log in output.log -t | --tests Test name you want to run specifically -h | --help Show this usage info EOF }

cd $BASE_DIR ROOT=$PWD for test in $TESTS; do run_$test done
