From c4d6a1b8e8ea79c439a4871cba540443c9eb13b9 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Thu, 21 Sep 2017 10:29:22 -0700 Subject: [PATCH] dm-raid: fix a race condition in request handling raid_map calls pers->make_request, which missed the suspend check. Fix it with the new md_handle_request API.
