If the caller is do_reset() or do_hard_reset(),  \nthey will release the resources on the next reset.  \n  \nThis fixes following crash that occurred when running the drmgr command  \nseveral times to add/remove a vnic interface:  \n  \n [102056] ibmvnic 30000003 env3: Disabling rx_scrq[6] irq  \n [102056] ibmvnic 30000003 env3: Disabling rx_scrq[7] irq  \n [102056] ibmvnic 30000003 env3: Replenished 8 pools  \n Kernel attempted to read user page (10) - exploit attempt?
