From: Xin Hao <xhao@linux.alibaba.com> mainline inclusion from mainline-v5.17-rc1 commit b627b774911660852ce7f3f3817955ddad2bd130 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4RTX9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- Patch series "mm/damon: Do some small changes", v4. This patch (of 4): In damon/paddr.c file, two functions names start with underscore, static void __damon_pa_prepare_access_check(struct damon_ctx *ctx, struct damon_region *r) static void __damon_pa_prepare_access_check(struct damon_ctx *ctx, struct damon_region *r) In damon/vaddr.c file, there are also two functions with the same function, static void damon_va_prepare_access_check(struct damon_ctx *ctx, struct mm_struct *mm, struct damon_region *r) static void damon_va_check_access(struct damon_ctx *ctx, struct mm_struct *mm, struct damon_region *r) It makes sense to keep consistent, and it is not easy to be confused with the function that call them.
