However, the update also involved the removal of approximately 13,000 lines of code related to legacy systems, including the elimination of a 40-year-old Hercules graphics card driver and the AppleTalk networking protocol.<\/p>\n<p>Notably, a much-anticipated GPU scheduler feature was removed last minute, reverting to the original first-in-first-out (FIFO) method due to performance issues reported on certain AMD graphics cards.<\/p>\n<h3>Key Features of Linux 7.2<\/h3>\n<p><strong>Cache-aware Scheduling:<\/strong><br \/>The task scheduler now recognizes when threads belong to the same process and keeps them on cores that share a cache, reducing cache bouncing and improving efficiency.<\/p>\n<p><strong>Pipes Locking Fix:<\/strong><br \/>A fix has been implemented to reduce the lock-holding time in pipes, enhancing performance by 6-28% and decreasing write latency by 5-22% in specific scenarios.<\/p>\n<p><strong>Memory Reclaim Enhancements:<\/strong><br \/>The Multi-Generational LRU (MGLRU) algorithm improvements lead to increased efficiency in memory reclamation, particularly benefiting workloads like MongoDB.<\/p>\n<p><strong>Ext4 Filesystem Improvements:<\/strong><br \/>Minor speed optimizations in ext4 enhance its performance, removing lock contention during heavy usage, and making directory lookups faster.<\/p>\n<p><strong>Other Filesystem Updates:<\/strong><br \/>Linux 7.2 improves NTFS and exFAT functionality, with NTFS now supporting proper symbolic links and exFAT seeing speed increases of up to 87% under heavy load. The Btrfs filesystem has also received performance optimizations.<\/p>\n<p><strong>USB4 Data Transfers:<\/strong><br \/>Support for USB4 data streaming allows for data transmission directly between devices over a compatible USB4 or Thunderbolt cable without requiring a network.<\/p>\n<p><strong>Proc Filesystem Speed Increase:<\/strong><br \/>The efficiency of reading certain files in the \/proc virtual filesystem has significantly improved, leading to faster performance for scripts and tools that probe system status.<\/p>\n<p><strong>Laptop Driver Improvements:<\/strong><br \/>Enhanced drivers for various laptops include better battery management for TUXEDO Computers, Surface Pro support, and improved functionality for Lenovo devices.<\/p>\n<p><strong>Peripheral Driver Enhancements:<\/strong><br \/>Linux 7.2 brings new support to various gaming peripherals and network adapters, enhancing compatibility and performance for Linux gamers.<\/p>\n<h3>Next Steps for Ubuntu 26.10<\/h3>\n<p>Canonical has indicated that Linux 7.2 is the targeted kernel version for Ubuntu 26.10. However, due to the timing of the release, the upcoming Linux 7.3 could also be a candidate, pending confirmation from Canonical\u2019s kernel engineers.<\/p>\n<p>For those interested in downloading Linux 7.2, the source code is available on <a target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/kernel.org\">kernel.org<\/a>. While this version won&#8217;t be an official software update for Ubuntu users, it can be installed via third-party PPAs or Canonical Mainline .deb packages, although this is generally not recommended due to potential stability concerns.<\/p>\n<p>For further insights on this release, details can be found in LWN\u2019s merge reports, and the entire commit history is available on <a target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/github.com\/torvalds\/linux\/tree\/v7.2\">GitHub<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Linux kernel 7.2 has been officially released, introducing several significant enhancements, including cache-aware scheduling, performance improvements for ext4 and Btrfs filesystems, and a&hellip;<\/p>\n","protected":false},"author":0,"featured_media":4014,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1372,38,1454,4,1455],"tags":[],"class_list":["post-4013","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ext4","category-linux-kernel","category-mediatek","category-news","category-realtek"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Discover Linux 7.2: Enhanced Performance with Cache-Aware Scheduling and Faster ext4 &amp;
