- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric
Dumazet makes TCP a little faster.
- The 9 patch series "liveupdate: Rework KHO for in-kernel users" from
Pasha Tatashin reworks the KEXEC Handover interfaces in preparation for
Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.
