X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d576d20ccdeffbb7ba28053107fa6f838b67f3a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm/swapfile.c: use list_for_each_entry_safe in free_swap_count_continuations

Use list_for_each_entry_safe() instead of list_for_each_safe() to
simplify the code.
