[PATCH 3/5] vhost-scsi: Remove vhost_scsi_mutex from port link/unlink
We don't need the vhost_scsi_mutex in vhost_scsi_port_link and vhost_scsi_port_unlink because LIO has a refcount on the se_tpg for us, so it can't be removed while these functions are called. This removes the vhost_scsi_mutex from those functions to avoid cases where we are adding or removing LUNs to vhost-deviceA but are stuck waiting on the vhost_scs...

If a user performs LIO LUN unmapping before the endpoint has been cleared then we can end up trying to free a bogus tmf struct if the TMF is still exucuting when we do the unmap. 2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi pointer set and we can end up trying to access a freed struct. 3.

[PATCH 0/5] vhost-scsi: Fix management operation hangs
The following patches were made over Linus tree and also apply over mst tree's vhost branch. The patches fix an issue where management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs but we hold that mutex during those management operations. So if you
