Good morning, this is Linux Kernel Daily for June 9th, 2026.
Today's kernel changes center on stabilizing Microsoft Hyper-V virtualization support, with Linus pulling in a substantial batch of fixes that address critical reliability and resource management issues.
The dominant theme is improving Hyper-V's handling of system stress and shutdown scenarios. Several commits in merge e92a762 focus on panic and kexec situations - ensuring the frame buffer flushes before VMBus unloads during panics, and properly cleaning up SynIC state during kexec operations for L1 virtual hosts.…
Memory management also sees important updates. The MSHV driver now supports one-gigabyte huge pages by breaking them into two-megabyte aligned chunks, which should improve performance for memory-intensive workloads. The driver also gets better resource tracking, limiting SynIC management to only MSHV-owned resources…
Several maintenance improvements round out the Hyper-V updates, including switching from deprecated string copy functions to safer alternatives in the KVP utilities, and adding proper error propagation in registration functions. These changes reduce potential security vulnerabilities and make…
