What would be the next window? This fix is already queued on my end: https://lore.kernel.org/qemu-devel/cover.1780072238.git.qemu_oss@crudebyte.com/ https://github.com/cschoenebeck/qemu/commits/9p.next And these fixes are yet to be queued: https://lore.kernel.org/qemu-devel/cover.1781287774.git.qemu_oss@crudebyte.com/ https://lore.kernel.org/qemu-devel/cover.1781361555.git.qemu_oss@crudebyte.com/ And of course this series here: https://lore.kernel.org/qemu-devel/cover.1781621428.git.qemu_oss@crudebyte.com/ At least I currently don't have further reports to work on. So all bugfix patches are posted. /Christian
