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.

struct sockaddr_in
{
sa_family_t sin_family;
in_port_t sin_port;
struct in_addr sin_addr;
uint8_t sin_zero[8];
};
sin_zero is probably a random number.
struct sockaddr_in6
{
sa_family_t sin6_family;
in_port_t sin6_port;
uint32_t sin6_flowinfo;
struct in6_addr sin6_addr;
uint32_t sin6_scope_id;
};
sin6_flowinfo and sin6_scope_id is probably a random number.
Random numbers cause the same server configuration check failed,
so let's initialize it.
