Hi Linus,

Please pull the following Kselftest fixes update for Linux 5.17-rc3

This Kselftest fixes update for Linux 5.17-rc3 consists of important fixes to several tests and documentation clarification on running mainline kselftest on stable releases. A few notable fixes:

- fix kselftest run hang due to child processes that haven't been terminated. Fix signals all child processes - fix false pass/fail results from vdso_test_abi, openat2, mincore - build failures when using -j (multiple jobs) option - exec test build failure due to incorrect build rule for a run-time created "pipe" - zram test fixes related to interaction with zram-generator to make sure zram test to coordinate deleted with zram-generator - zram test compression ratio calculation fix and skipping max_comp_streams. - increasing rtc test timeout - cpufreq test to write test results to stdout which will necessary on automated test systems

diff is attached.

thanks, -- Shuah
