reason:
We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.
up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.
up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.

The commit c4d8d937d5 added null byte for
obstack_vprintf and thus to obstack_printf. I probably lost my marbles
but the same test I run previously now won't append null byte at the end
and this "fix" now causes regressions in code using obstack.
For the reference this is the testing code:
#define _GNU_SOURCE
#include <obstack.h>
#include <stdarg.h>
#include <stdio.h>
#include <stdlib.h>
#define obstack_chunk_alloc malloc
#define obstack_chunk_free free
static void print(struct obstack *obs, const char *fmt, ...) {
va_list arg;
va_start(arg, fmt);
obstack_vprintf(obs, fmt, arg);
va_end(arg);
}
int main(int argc, char *argv[]) {
struct obstack obs;
obstack_init(&obs);
obstack_printf(&obs, "this %s", "text ");
obstack_printf(&obs, "is appended");
print(&obs, " as well as %s", "vprintf text");
obstack_1grow(&obs, '\0');
printf("%s\n", (char *)obstack_finish(&obs));
obstack_free(&obs, NULL);
return 0;
