2019-07-30nvme-multipath: revalidate nvme_ns_head gendisk in nvme_validate_nsAnthony Iliopoulos
When CONFIG_NVME_MULTIPATH is set, only the hidden gendisk associated with the per-controller ns is run through revalidate_disk when a rescan is triggered, while the visible blockdev never gets its size (bdev->bd_inode->i_size) updated to reflect any capacity changes that may have occurred. This prevents online resizing of nvme block devices and in extension of any filesystems atop that will are unable to expand while mounted, as userspace relies on the blockdev size for obtaining the disk capacity (via BLKGETSIZE/64 ioctls). Fix this by explicitly revalidating the actual namespace gendisk in addition to the per-controller gendisk, when multipath is enabled.

2019-07-30drm/i915/gvt: Adding ppgtt to GVT GEM context after shadow pdps settled.Colin Xu
Windows guest can't run after force-TDR with host log: ... gvt: vgpu 1: workload shadow ppgtt isn't ready gvt: vgpu 1: fail to dispatch workload, skip ... The error is raised by set_context_ppgtt_from_shadow(), when it checks and found the shadow_mm isn't marked as shadowed. In work thread before each submission, a shadow_mm is set to shadowed in: shadow_ppgtt_mm() <-intel_vgpu_pin_mm() <-prepare_workload() <-dispatch_workload() <-workload_thread() However checking whether or not shadow_mm is shadowed is prior to it: set_context_ppgtt_from_shadow() <-dispatch_workload() <-workload_thread() In normal case, create workload will check the existence of shadow_mm, if not it will create a new one and marked as shadowed. If already exist it will reuse the old one. Since shadow_mm is reused, checking of shadowed in set_context_ppgtt_from_shadow() actually always see the state set in creation, but not the state set in intel_vgpu_pin_mm(). When force-TDR, all engines are reset, since it's not dmlr level, all ppgtt_mm are invalidated but not destroyed. Invalidation will mark all reused shadow_mm as not shadowed but still keeps in ppgtt_mm_list_head. If workload submission phase those shadow_mm are reused with shadowed not set, then set_context_ppgtt_from_shadow() will report error. Pin for context after shadow_mm pinned and shadow pdps settled. v2: Move set_context_ppgtt_from_shadow() after prepare_workload().

2019-07-29mlxsw: spectrum_ptp: Increase parsing depth when PTP is enabledPetr Machata
Spectrum systems have a configurable limit on how far into the packet they parse. By default, the limit is 96 bytes. An IPv6 PTP packet is layered as Ethernet/IPv6/UDP (14+40+8 bytes), and sequence ID of a PTP event is only available 32 bytes into payload, for a total of 94 bytes. When an additional 802.1q header is present as well (such as when ptp4l is running on a VLAN port), the parsing limit is exceeded. Such packets are not recognized as PTP, and are not timestamped. Therefore generalize the current VXLAN-specific parsing depth setting to allow reference-counted requests from other modules as well. Keep it in the VXLAN module, because the MPRS register also configures UDP destination port number used for VXLAN, and is thus closely tied to the VXLAN code anyway. Then invoke the new interfaces from both VXLAN (in obvious places), as well as from PTP code, when the (global) timestamping configuration changes from disabled to enabled or vice versa.
