Subject: fix a pmem regression due to drain the block queue in del_gendisk
Date: Tue, 19 Oct 2021 09:36:39 +0200 [thread overview]
Message-ID: <20211019073641.2323410-1-hch@lst.de> (raw)
Hi Dan,
this series fixes my recently introduced regression in the pmem driver by
removing the usage of q_usage_count as the external pgmap refcount in the
pmem driver and then removes the now unused external refcount
infrastructure.
