名称	描述
set_current_blocked	set_current_blocked - change current->blocked mask@newset: new mask It is wrong to change ->blocked directly, this helper should be used* to ensure the process can't miss a shared signal we are going to block.
sigprocmask	This is also useful for kernel threads that want to temporarily* (or permanently) block certain signals.* NOTE! Unlike the user-mode sys_sigprocmask(), the kernel* interface happily blocks "unblockable" signals like SIGKILL* and friends.
