Commit 49f6b93d07 for qemu.org
commit 49f6b93d0752b91c233ae8097d00a986cb8482c3
Author: Shameer Kolothum <skolothumtho@nvidia.com>
Date: Wed Jan 21 11:41:09 2026 +0000
linux-headers: Update to Linux v6.19-rc1
Mainly for adding support for VFIO DMABUF. While at it, update all
headers.
The header update breaks virtio-net due to virtio_net_hdr_v1_hash
changes. Include the virtio-net changes to avoid build and bisect
failures.
