The Linux kernel version 6.18.7 has been officially released, bringing significant enhancements aimed at boosting stability and performance. Key updates include improvements to memory management, particularly for systems utilizing multiple processors (Symmetric Multi-Processing, SMP). A critical fix was implemented to address potential memory corruption in the page allocator when interrupts were disabled, achieved by modifying the lock acquisition method to use spin_lock_irqsave().
Additionally, the kernel now optimizes the process of freeing pages within the decay_pcp_high function. By adopting a batching approach, the kernel mitigates the risk of resource hogging that could lead to system stalls during high-demand scenarios. Furthermore, an earlier adjustment concerning functionfs was reversed to resolve compatibility issues affecting some Android devices, ensuring a smoother user experience without compromising overall progress.

Linux Kernel 6.18.7 released
The Linux kernel version 6.18.7 has been released with several key updates aimed at improving stability and performance. One change addresses potential memory corruption issues in systems using multiple processors by updating how locks are acquired, specifically through the use of spin_lock_irqsave(). Another update optimizes page freeing within the decay_pcp_high function, now using batching to prevent resource hogs that could stall system components. Additionally, a previous update related to functionfs was reversed to address compatibility issues and prevent disruptions on some Android devices.
