名称描述
flush_sigqueue_maskRemove signals in mask from the pending set and queue.* Returns 1 if any signals were found.* All callers must be holding the siglock.
__set_task_blocked
sigprocmaskThis 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.
