From af21bfaf70a1358f306588232f741b292d9be5a7 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 6 Jul 2017 07:02:19 -0400 Subject: [PATCH] mm: fix mapping_set_error call in me_pagecache_dirty The error code should be negative. Since this ends up in the default case anyway, this is harmless, but it's less confusing to negate it. Also, later patches will require a negative error code here.
