From 0f646425b94a01606450eb03b3a8f3b5e03ea9b8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 4 Jan 2016 10:11:01 +0000 Subject: [PATCH] drm: Use a normal idr allocation for the obj->name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unlike the handle, the name table uses a sleeping mutex rather than a spinlock. The allocation is in a normal context, and we can use the simpler sleeping gfp_t, rather than have to take from the atomic reserves.
