Description

Although "ctx_budget = NULL" && "initialize the op->ctx_budgeted = false" assertions will not trigger calls * ctx_budget appear ,
But the user doesn't have to understand this relationship, therefore may appear op - > ctx_budgeted is set to true, the trigger to get address blank

ceph_tid_t Objecter::_op_submit_with_budget(Op *op, RWLock::Context& lc, int *ctx_budget)
{
  ...
  if (!op->ctx_budgeted || (ctx_budget && (*ctx_budget == -1))) {
    int op_budget = _take_op_budget(op);
    // take and pass out the budget for the first OP
    // in the context session
    if (ctx_budget && (*ctx_budget == -1)) {
      *ctx_budget = op_budget;
    }
  }
