Linux Kernel Rejects Xiaomi Engineer’s UFS File‑Based Optimization Patch

A Xiaomi engineer submitted a set of Linux kernel patches to implement JEDEC’s UFS File‑Based Optimization (UFS FBO) for better storage performance, but kernel maintainer Christoph Hellwig harshly criticized the proposal as completely misguided and unrelated to the kernel, making acceptance unlikely.

UFS File-Based Optimization (FBO) Standard and Its Controversial Linux Kernel Patch

JEDEC’s new UFS File‑Based Optimization (FBO) 1.0 standard defines an interface for host‑device communication to defragment file‑related LBA ranges, but a Xiaomi engineer’s Linux kernel patch implementing it was sharply criticized by kernel veteran Christoph Hellwig as impractical and unrelated to the kernel.
