Hi...
I am new to Linux MM. Can someone answer my following questions?
I'll try...
1> Where is the process page table(mm->pgd) stored? Is it stored below
PAGE_OFFSET ?
Above PAGE_OFFSET, in other word... it's inside kernel space, just like
the task_struct descriptor.
If yes, then wouldn't there
be a chance of the page tables getting accidentally corrupted by the user
process as it is in the user address space?
2> What will happen if the page containing the process page table(mm->pgd)
is swapped on the disk and the process is scheduled for execution ?
Since it's in kernel space, it won't be swapped out.
regards,
Mulyadi
