Subject: [PATCH] nvme: flush scan work on passthrough commands
Date: Thu, 30 Apr 2020 05:31:23 +0900 [thread overview]
Message-ID: <20200429203123.31302-1-kbusch@kernel.org> (raw)
If a passthrough command causes the namespace inventory or capabilities
to change, flush the scan work that handles these changes so the driver
synchronizes with the user command's effects before returning the result
to user space.
