-Subject: [PATCH] pci-assign: sync MSI/MSI-X cap and table with PCIDevice
-
-Since commit e1d4fb2d ("kvm-irqchip: x86: add msi route notify fn"),
-kvm_irqchip_add_msi_route() starts to use pci_get_msi_message() to fetch
-MSI info. This requires that we setup MSI related fields in PCIDevice.
-For most devices, that won't be a problem, as long as we are using
-general interfaces like msi_init()/msix_init().
-
-However, for pci-assign devices, MSI/MSI-X is treated differently - PCI
-assign devices are maintaining its own MSI table and cap information in
-AssignedDevice struct. however that's not synced up with PCIDevice's
-fields. That will leads to pci_get_msi_message() failed to find correct
-MSI capability, even with an NULL msix_table.
-
-A quick fix is to sync up the two places: both the capability bits and
-table address for MSI/MSI-X.

-Subject: [PATCH] virtio: zero vq->inuse in virtio_reset()
-
-vq->inuse must be zeroed upon device reset like most other virtqueue
-fields.
-
-In theory, virtio_reset() just needs assert(vq->inuse == 0) since
-devices must clean up in-flight requests during reset (requests cannot
-not be leaked!).
-
-In practice, it is difficult to achieve vq->inuse == 0 across reset
-because balloon, blk, 9p, etc implement various different strategies for
-cleaning up requests.  Most devices call g_free(elem) directly without
-telling virtio.c that the VirtQueueElement is cleaned up.  Therefore
-vq->inuse is not decremented during reset.
-
-This patch zeroes vq->inuse and trusts that devices are not leaking
-VirtQueueElements across reset.
-
-I will send a follow-up series that refactors request life-cycle across
-all devices and converts vq->inuse = 0 into assert(vq->inuse == 0) but
-this more invasive approach is not appropriate for stable trees.

-Subject: [PATCH] scsi: mptsas: use g_new0 to allocate MPTSASRequest object
-
-When processing IO request in mptsas, it uses g_new to allocate
-a 'req' object. If an error occurs before 'req->sreq' is
-allocated, It could lead to an OOB write in mptsas_free_request
-function. Use g_new0 to avoid it.
