The downside is that backporting affected patches to older kernel branches now fails with error messages such as mm/kfence/core.c: In function ‘kfence_init_pool’: mm/kfence/core.c:595:2: error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode Just something to keep in mind when writing patches.
