From e485382ea7eb4b81f4b59073cd831084820497de Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Thu, 2 Dec 2021 11:29:08 +0100 Subject: [PATCH] drm/ttm: fix ttm_bo_swapout MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 7120a447c7fe ("drm/ttm: Double check mem_type of BO while eviction") made ttm_bo_evict_swapout_allowable() function actually check the placement, but we always used a dummy placement in ttm_bo_swapout. Fix this by using the real placement instead.
