Each resume therefore replaces the boot-time pointers\nand leaks both old allocations. The function also uses GFP_KERNEL from a\nsyscore resume callback, where interrupts are disabled and the non-boot\nCPUs are offline.\n\nReturn early if both buffers are already allocated. Clear the pointers\nin free_ga_log() so a partial allocation failure cannot leave ga_log\ndangling."
