From c1ca59a1f21e360b26e26c187a4e42f22bb768d3 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 25 Feb 2021 17:18:45 -0800 Subject: [PATCH] mm/backing-dev.c: use might_alloc() Now that my little helper has landed, use it more. On top of the existing check this also uses lockdep through the fs_reclaim annotations.
