__get_insn_slot() allocates 'struct kprobe_insn_page' using a custom structure size calculation macro, KPROBE_INSN_PAGE_SIZE. Replace KPROBE_INSN_PAGE_SIZE with the struct_size() macro, which is the preferred way to calculate the size of flexible structures in the kernel because it handles overflow and makes it easier to change and audit how flexible structures are allocated across the entire tree.
