From 1d68b96800efb58f1cec547fc3a2e07539ef951e Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Fri, 5 Nov 2021 13:47:07 -0700 Subject: [PATCH] UPSTREAM: mm/damon/vaddr: constify static mm_walk_ops The only usage of these structs is to pass their addresses to walk_page_range(), which takes a pointer to const mm_walk_ops as argument. Make them const to allow the compiler to put them in read-only memory.
