During boot of kernel with CONFIG_KASAN the following KASAN false positive failure will occur when ibft_init() reads the ACPI iBFT table: BUG: KASAN: use-after-free in ibft_init
The ACPI iBFT table is not allocated, and the iscsi driver uses a pointer to it to calculate checksum, etc. KASAN complains about this pointer with use-after-free, which this is not.
