名称	描述
do_debug	Our handling of the processor debug registers is non-trivial.* We do not clear them on entry and exit from the kernel. Therefore* it is possible to get a watchpoint trap here from inside the kernel.* However, the code in

enable_single_step	Enable single-stepping. Return nonzero if user mode is not using TF itself.
set_task_blockstep
user_disable_single_step
copy_process	创建进程
__exit_signal	This function expects the tasklist_lock write-locked.
__ptrace_unlink	__ptrace_unlink - unlink ptracee and restore its execution state@child: ptracee to be unlinked Remove @child from the ptrace list, move it back to the original parent,* and restore the execution state so that it conforms to the group stop* state

flush_signals	Flush all pending signals for this kthread.
klp_try_switch_task	Try to safely switch a task to the target patch state. If it's currently* running, or it's sleeping on a to-be-patched or to-be-unpatched function, or* if the stack is unreliable, return false.
klp_try_complete_transition	Try to switch all remaining tasks to the target patch state by walking the* stacks of sleeping tasks and looking for any to-be-patched or* to-be-unpatched functions. If such functions are found, the task can't be* switched yet.
klp_reverse_transition	This function can be called in the middle of an existing transition to* reverse the direction of the target patch state. This can be done to* effectively cancel an existing enable or disable operation if there are any
audit_alloc	安全审计
uprobe_deny_signal	If we are singlestepping, then ensure this thread is not connected to* non-fatal signals until completion of singlestep. When xol insn itself* triggers the signal, restart the original insn even if the task is
user_return_notifier_unregister	Removes a registered user return notifier. Must be called from atomic* context, and from the same cpu registration occurred in.
