From 548d9782bd844048bc6b5159c848772a5fe3da32 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Tue, 13 Oct 2020 16:52:21 -0700 Subject: mm/page_io.c: remove useless out label in __swap_writepage() The out label is only used in one place and return ret directly without something like resource cleanup or lock release and so on. So we should remove this jump label and do some cleanup.
