FYI, we noticed the below changes on

git://git.infradead.org/users/hch/block.git nvme-loop.2
commit c1a6680dfd43af25bdfd5a22a7fe6efc16ba56f6 ("block: defer timeouts to a workqueue")

As below, just FYI.  Although the memory size of virtual machine is too
small, your commit may increased memory usage.
