Hi Linus,

Please pull the following Kselftest update for Linux 6.4-rc1.

This Kselftest update for Linux 6.4-rc1 consists of:

- several patches to enhance and fix resctrl test - nolibc support for kselftest with an addition to vprintf() to tools/nolibc/stdio and related test changes - Refactor 'peeksiginfo' ptrace test part - add 'malloc' failures checks in cgroup test_memcontrol - a new prctl test - enhancements sched test with additional ore schedule prctl calls

diff is attached.

thanks, -- Shuah
