No reference is taken across that\nwindow, so a concurrent qla24xx_deallocate_vp_id() can tear the vport\ndown and free it, leading to a use-after-free.\n\nTake a vport reference (vref_count) under vport_slock when the matching\nvp is found, and drop it after the last use of\nvp. qla24xx_deallocate_vp_id() waits for vref_count to reach zero before\nunlinking and freeing the vport, so the pointer stays valid.
