From 46dc967445bde5300eee7e567a67796de2217586 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 30 Mar 2022 07:29:11 +0200 Subject: [PATCH] loop: don't freeze the queue in lo_release By the time the final ->release is called there can't be outstanding I/O. For non-final ->release there is no need for driver action at all. Thus remove the useless queue freeze. Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Tested-by: Darrick J.
