    SubjectRe: [PATCH rcu 0/27] Unconditionally enable SRCU
    Hello!

    This v2 series removes Kconfig "select" clauses and #ifdef directives that
    are no longer necessary give that SRCU is now unconditionally enabled,
    courtesy of new-age printk() requirements. Finally, the SRCU Kconfig
    option is removed entirely.

    1. arch/x86: Remove "select SRCU".

    2. drivers/base: Remove CONFIG_SRCU.

    3. drivers/cpufreq: Remove "select SRCU".

    4. drivers/dax: Remove "select SRCU".

    5. drivers/hwtracing/stm: Remove "select SRCU".

    6. drivers/md: Remove "select SRCU".

    7. drivers/net: Remove "select SRCU".

    8. drivers/pci/controller: Remove "select SRCU".

    9. fs: Remove CONFIG_SRCU.

    10. fs/btrfs: Remove "select SRCU".

    11. fs/dlm: Remove "select SRCU".

    12. fs/notify: Remove "select SRCU".

    13. fs/quota: Remove "select SRCU".

    14. init: Remove "select SRCU".

    15. kernel/notifier: Remove CONFIG_SRCU.

    16. kernel/power: Remove "select SRCU".

    17. kvm: Remove "select SRCU".

    18. mm: Remove "select SRCU".

    19. tomoyo: Remove "select SRCU".

    20. Remove CONFIG_SRCU.

    Changes since v1:

    o Added ack and review tags.

    o Dropped patches taken by their maintainers.

    o Combined the KVM-related commits into a single commit, as requested
    by Sean Christopherson. Acks received thus far are qualified by
    the corresponding architecture.

    o Added the tomoyo patch based on feedback from Nick Desaulniers.

    Thanx, Paul
