User data within the process address space must be accessed using kernelservices.
对于进程地址空间中的用户数据,必须使用内核服务进行访问。
2
The setjmpx and longjmpx kernelservices maintain the AMR and the context stack pointer.
longjmpx 和 frr_add 内核服务可以维护 AMR 和上下文堆栈指针。
3
The service can be used by remote filesystems or other kernelservices to manage cryptography, authentication tokens, cross-domain user mappings, and other security concerns.
