Why are processes without an mm pointer called lazy TLB processes? Suppose that the process that runs after a kernel thread is the same process that has run before. In this case, the kernel does not need to modify the userspace address tables, and the information in the translation lookaside buffers is still valid. A switch (and a corresponding clearance of TLB data) is only required when a different userland process from before executes after the kernel thread.
마지막 문장에서 from before executes after the kernel thread. 이 부분은 어떻게 해석해야 하나요?
from / before / ... / after / ... 와 같이 부사가 연달아 등장하니까 어렵습니다.
도움 부탁드립니다.
