From 75aad5ffe099a1b1a342257236dc260493917ed2 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 13 Jan 2026 16:58:00 +0800 Subject: [PATCH] selftests/ublk: fix IO thread idle check Include cmd_inflight in ublk_thread_is_done() check. Without this, the thread may exit before all FETCH commands are completed, which may cause device deletion to hang.
