Dmitriy Govorukhin updated IGNITE-11786:
----------------------------------------
Description:
The new structure should work as a stack.
When thread obtains lock we push pageId (+meta) on the top of the stack when
thread release lock we pop pageId from the stack. Their cases when thread may
unlock page not from current thread frame (some split pages in B-tree), from
previous, in this case, we should go down to stack and find this page and
update meta.
{code}
public interface LockStack {
void push(int cacheId, long pageId, int flags);
void pop(int cacheId, long pageId, int flags);
int R = 1;
int W = 2;
}
{code}
