Re: [PATCH 10/13] vfio/mbochs: Fix close when multiple device FDs are open

On Wed, Jul 14 2021, Jason Gunthorpe jgg@nvidia.com wrote:

mbochs_close() iterates over global device state and frees it. Currently this is done every time a device FD is closed, but if multiple device FDs are open this could corrupt other still active FDs.

Change this to use close_device() so it only runs on the last close.
