Hello everyone, I have some questions about page allocation and locking. - Suppose that a process is about to be killed and before that happens, I want to keep the content of the page intact in the memory, i.e. the page should neither be zeored or allocated to some other process unless required. In order to achieve this, what can be the most optimal approach in which the internals of the kernel is not changed besides adding a syscall or something. - Another is what happens if I increase the count of mm_users and mm_count before and later that process gets killed. Assuming that the mm was linked only to the killed process. What will happen in this case? - Last question that I wanted to know is what will happen if I change the flags of the pages to be reserved and unevictable? Is it possible for the pages to be set pinned as well? Can this approach help me soling the first issue or I might get a BUG by some other component in kernel? Since, I have just started playing with the kernel, so there is a possibility that I might have asked something very silly/horrific. Please bear with me.
