,----[ xin-tong ]
| where is user:stack-segment-size defined ?
`----
that is computable once again :) (assuming x86, and 1+3 split)
user:stack-segment-size = ((unsigned long)(0xc0000000 - user:start-stack)) >> PAGE_SHIFT
kind regards

| | I am trying to find the start and end address of the userspace
| stack.
| | I see in the task_struct there is start_stack. But I could not
| find
| | end_start anywhere in the kernel code ?
| |
| | Can someone please tell me how to find the end of the stack ?
|
| `----
| but that should be computable right e.g.
| user:stack-end = user:stack-start + user:stack-segment-size *
| number-of-pages
