[PATCH] mm: Remove reference to destructor in comment in calculate_sizes()

From: William Kucharski

Date: Tue Oct 21 2025 - 07:00:26 EST


The commit that removed support for destructors from kmem_cache_alloc()
never removed the comment regarding destructors in the explanation
of the possible relocation of the free pointer in calculate_sizes().

Fixes: 20c2df83d25c ("mm: Remove slab destructors from kmem_cache_create().")
