    Subject[PATCH kcsan 02/29] kcsan: Remove redundant zero-initialization of globals
    Date
    From: Marco Elver <elver@google.com>

    They are implicitly zero-initialized, remove explicit initialization.
    It keeps the upcoming additions to kcsan_ctx consistent with the rest.

    No functional change intended.
