A pool failure jumps to out_free_buffer_pools without\nh_free_logical_lan(), so PHYP still owns the buffer-list page when\nit is unmapped. request_irq() failure already issued the hypercall\nbefore taking the same label.\n\nMove that h_free to the shared post-register unwind so both paths\nderegister before the buffer list is unmapped.",
