Maintainer Ted Ts'o highlighted changes allowing parallel direct I/O writes by relaxing overly conservative exclusive-lock checks, faster ext4_mb_prefetch() in the multi-block allocator via fallocate(), and improved overwrite performance on up-to-date folios. The pull also includes code clean-ups, fixes for possible soft lockups or RCU stall conditions, and various bug fixes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What EXT4 performance improvements are coming in Linux 7.3? Linux 7.3 improves EXT4 performance by allowing parallel direct I/O writes, since earlier code was overly conservative in checking whether an exclusive lock was needed. It also speeds up ext4_mb_prefetch() in the multi-block allocator by using fallocate() to skip unnecessary work, and improves performance for overwrites to already up-to-date folios. _Track kernel filesystem changes like these EXT4 tweaks as you plan upgrades on daily.dev._ ### Who submitted the main EXT4 feature pull request for Linux 7.3? EXT4 maintainer Ted Ts'o submitted the main EXT4 feature pull request for Linux 7.3, which includes performance optimizations, code clean-ups, fixes for possible soft lockups or RCU stall conditions, and a variety of bug fixes. _Follow kernel maintainer pull requests like this one on daily.dev to stay ahead of filesystem changes._ ## Similar posts on daily.dev - [EXT4 In Linux 7.0 Improves Write Performance For Concurrent Direct I/O Writes](https://daily.dev/posts/ext4-in-linux-7-0-improves-write-performance-for-concurrent-direct-i-o-writes-z5kk6zl4o) · Phoronix · 0 upvotes · 0 comments - [IOmap Improvement For Linux 7.3 Takes EXT4 & XFS Performance Further](https://daily.dev/posts/iomap-improvement-for-linux-7-3-takes-ext4-xfs-performance-further-ayzsohqii) · Phoronix · 0 upvotes · 0 comments - [Btrfs Ready With More Performance Improvements For Linux 7.3: Some ~3x To ~5x Wins](https://daily.dev/posts/btrfs-ready-with-more-performance-improvements-for-linux-7-3-some-3x-to-5x-wins-b4x0ludw1) · Phoronix · 1 upvotes · 0 comments - [Someone moved three lines of code in Linux 7.2 and got a 5% storage speed boost](https://daily.dev/posts/someone-moved-three-lines-of-code-in-linux-7-2-and-got-a-5-storage-speed-boost-4juxmldkx) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#performance](https://daily.dev/tags/performance) [View this post on daily.dev](https://daily.dev/posts/ext4-preps-more-performance-improvements-for-linux-7-3-xhnbgosyd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"EXT4 Preps More Performance Improvements For Linux 7.3","url":"https://daily.dev/posts/ext4-preps-more-performance-improvements-for-linux-7-3-xhnbgosyd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/ext4-preps-more-performance-improvements-for-linux-7-3-xhnbgosyd"},"datePublished":"2026-08-20T01:04:47.720Z","dateModified":"2026-08-20T01:22:27.255Z","description":"The main EXT4 feature pull request for Linux 7.3 has been submitted, adding further performance optimizations on top of earlier IOmap improvements.
