Linux Kernel: VFS Spring Cleaning - Fixes Galore and Stability Wins
Today we're diving into a substantial VFS fixes merge from Linus himself, pulling in improvements from Christian Brauner's team. This release candidate 8 merge tackles everything from FUSE filesystem race conditions to delegation handling across multiple filesystems, plus some nice performance optimizations for writeback operations.

Hey there, kernel explorers! Welcome back to another episode of Linux Kernel - I'm your host, and wow, do we have some satisfying cleanup work to talk about today. You know those days when you finally tackle that growing list of small but important fixes? That's exactly what happened in the kernel world yesterday,…
So Linus pulled in a big batch of VFS fixes from Christian Brauner, and let me tell you - this is the kind of merge that might not make headlines, but it's absolutely critical for keeping our filesystems running smoothly. We're talking about fixes across FUSE, NFS, Ceph, GFS2, and several other filesystems. It's…
The star of the show here is definitely the FUSE filesystem work. The team tackled some gnarly race conditions around stale dentry cleanup - and if you're not familiar with dentries, think of them as the kernel's way of caching directory entries to speed up file lookups. The problem was there was a race condition…
Here's something that caught my eye - they fixed an issue with delegation requests on directories across multiple filesystems. Basically, several filesystem drivers were accidentally allowing delegation requests on directories when they should only…
And…
