Matheus Alves de Almeida changed the allocation code path used when growing a file with the FALLOC_FL_KEEP_SIZE flag, which pre-allocates disk space without changing the reported file size. Previously the driver performed many one-cluster allocations; the fix allocates multiple clusters in a single call. The patches were merged this week into Linux 7.4 via the non-MM pull request sent by Andrew Morton. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did FAT32 file allocation get so much faster in Linux 7.4? A patch from Matheus Alves de Almeida changed the FAT driver's allocation code path so it allocates multiple clusters in one call instead of performing many separate one-cluster allocations. This mainly benefits file growth using the FALLOC_FL_KEEP_SIZE flag, which pre-allocates disk space without changing the reported file size, yielding up to a 265x speed-up in benchmarks. The patch was merged into Linux 7.4 via Andrew Morton's non-MM pull request. _Kernel watchers tracking file-system performance changes like this follow Linux patch coverage on daily.dev._ ## Similar posts on daily.dev - [exFAT For Linux 7.1 Helps Reduce File Fragmentation, Fixes](https://daily.dev/posts/exfat-for-linux-7-1-helps-reduce-file-fragmentation-fixes-fec1skdhm) · Phoronix · 0 upvotes · 0 comments - [exFAT File-System Enjoys Better Performance On Linux 7.2 With IOmap Conversion](https://daily.dev/posts/exfat-file-system-enjoys-better-performance-on-linux-7-2-with-iomap-conversion-aedybxzir) · Phoronix · 2 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 - [Upcoming exFAT Linux Driver Patch Can Boost Sequential Read Performance By ~10%](https://daily.dev/posts/upcoming-exfat-linux-driver-patch-can-boost-sequential-read-performance-by-10--uu4lrpnlp) · Phoronix · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/fat32-file-system-seeing-as-much-as-265x-improvement-with-linux-7-4-yjqx16bkd) ```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":"FAT32 File-System Seeing As Much As 265x Improvement With Linux 7.4","url":"https://daily.dev/posts/fat32-file-system-seeing-as-much-as-265x-improvement-with-linux-7-4-yjqx16bkd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/fat32-file-system-seeing-as-much-as-265x-improvement-with-linux-7-4-yjqx16bkd"},"datePublished":"2026-10-29T10:12:35.932Z","dateModified":"2026-10-29T10:13:21.095Z","description":"A small patch to the FAT driver delivers up to a 265x improvement for FAT32.
