Currently, after generating run_kselftest.sh, there is no way to choose
which test we could run. All the tests are listed together and we have
to run all every time. This patch enhanced the run_kselftest.sh to make
the tests individually selectable. e.g.

  $ ./run_kselftest.sh -t "bpf size timers"

Before the patch:
================

$ cat 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:
===============

$ cat run_kselftest.sh
\#!/bin/sh
BASE_DIR=$(realpath $(dirname $0))
. ./kselftest/runner.sh
TESTS="android ...<snip>... filesystems/binderfs ...<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_filesystems_binderfs()
{
        [ -w /dev/kmsg ] && echo "kselftest: Running tests in filesystems/binderfs" >> /dev/kmsg
        cd filesystems/binderfs
        run_many        \
                "binderfs_test"
        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

        -s | --summary          Only print summary info and put detailed log in output.log

}

while true; do
        case "$1" in
        -s | --summary ) logfile=$BASE_DIR/output.log; cat /dev/null > $logfile; shift ;;
        -t | --tests ) TESTS=$2; shift 2 ;;
	-l | --list ) echo $TESTS; exit 0 ;;
        -h | --help ) usage; exit 0 ;;
        "" ) break;;
        * ) usage; exit 1;;
        esac
done

cd $BASE_DIR
ROOT=$PWD
for folder in $TESTS; do
        folder=$(echo $folder | tr -s '/-' '_')
        run_$folder
done

v5:
Forgot to update commit description for the new added -l option

v4:
Add parameter -l to list available tests, suggested by Bird, Tim

v3:
1) rebase the patch to latest code
2) move `tr -s "/-" "_"` in for loop at the end so user could use test
   folder name directly. Before the fix, user need to use
   ./run_kselftest.sh -t 'networking_forwarding'. Now they can just run
   ./run_kselftest.sh -t 'networking/forwarding' directly.

v2: update document and commit description.

Yes, please revert this patch. The resulting script is completely
trashed:

BASE_DIR=$(realpath $(dirname $0))
. ./kselftest/runner.sh
TESTS="seccomp"

run_seccomp()
{
-e      [ -w /dev/kmsg ] && echo "kselftest: Running tests in seccomp" >> /dev/kmsg
-e      cd seccomp
-en     run_many
        \
-ne             "seccomp_bpf"
        \
-ne             "seccomp_benchmark"

-e      cd $ROOT
}

I've sent an alternative that I think should do nicely. It will work
well with LAVA as well.

I'm really sorry to make this trouble. And I'm OK to revert the patch.
I just a little wondering how do you generate this script.
I tested with 'make -C tools/testing/selftests gen_tar FORMAT=.xz' before
post the patch and all looks good to me.

```

run_seccomp()
{
        [ -w /dev/kmsg ] && echo "kselftest: Running tests in seccomp" >> /dev/kmsg
        cd seccomp
        run_many        \
                "seccomp_bpf"   \
                "seccomp_benchmark"
        cd $ROOT
}

```

Thanks

This issue is with which shell is used. I suspect your /bin/sh is full
/bin/bash, where as Naresh's, the CI's, and mine are /bin/dash (which
lacks "-e" support for the built-in "echo").

Ah, got it. Thanks for your explanation.
