From ce162bfbc0b601841886965baba14877127c7c7c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 24 Jan 2018 08:40:51 +0100 Subject: [PATCH] mac80211_hwsim: don't use WQ_MEM_RECLAIM We're obviously not part of a memory reclaim path, so don't set the flag. This also causes a warning in check_flush_dependency() since we end up in a code path that flushes a non-reclaim workqueue, and we shouldn't do that if we were really part of reclaim.
