From cb93e597779e565dfeda34aede83c2565ddadc97 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 15 Aug 2017 22:20:37 +0300 Subject: [PATCH] cm: Don't allocate ib_cm workqueue with WQ_MEM_RECLAIM create_workqueue always creates the workqueue with WQ_MEM_RECLAIM and silences a flush dependency warn for WQ_LEGACY. Instead, we want to keep the warn in case the allocator tries to flush the cm workqueue because its very likely that cm work execution will yield memory allocations (for example cm connection requests).
