Why is it that several entries in the definition of INIT_TASK are listed
as zero? AFAIK every compiler zeroes the missing elements in case of
an incomplete struct initializer.

If it matters, a lot of members needing a zero initialization seem to be
missing otherwise.

arch/i386/kernel/init_task.c:
union task_union init_task_union
        __attribute__((__section__(".data.init_task"))) =
                { INIT_TASK(init_task_union.task) };

include/linux/sched.h:

#define INIT_TASK(tsk) \
{ \
    state: 0, \
    flags: 0, \
    sigpending: 0, \
    .
    .
    mm: NULL, \
    .
    .
    keep_capabilities: 0, \
    .
    .
    signal: {{0}}, \
    blocked: {{0}}, \
    .
    .
    sigqueue: NULL, \
    .
    .
}
