KSMBD PROTOCOL FIXES LAND IN 7.2-RC, GFS2 QUOTA BUGS SQUASHED

By RepoJournal · Filed 06:02 UTC on June 27, 2026 · About Linux

The kernel's SMB server implementation got a major protocol compliance overhaul after smbtorture exposed significant divergence from spec, while filesystems and power management shore up edge cases before the 7.2 release.

SMB3 support in ksmbd just got a correctness pass that rewrites lease state handling, oplock behavior, durable handle tracking, and CREATE/rename semantics to match actual protocol requirements [1]. This wasn't theoretical: smbtorture found real divergence that would break interop with strict clients. In parallel, GFS2 fixed a dangerous page poisoning bug during file growth and resolved quota initialization issues that were sleeping under bitlocks on PREEMPT_RT systems [2], which would deadlock real deployments. Thermal and power management got focused fixes: Intel's thermal_throttle driver no longer leaks resources on failure [3], and the schedutil governor's need_freq_update flag now clears correctly in the adjust_perf path to avoid spurious cpufreq calls [4]. eCryptfs received cleanup work replacing kmalloc/snprintf with kasprintf, reducing code footprint [5]. None of these are flashy, but they're the kind of subtle correctness fixes that prevent production headaches.

Action items

→ Test SMB3 workloads against 7.2-rc with strict Windows/Samba clients to verify oplock and lease fixes don't regress your workflows torvalds/linux [plan]
→ If running GFS2 on PREEMPT_RT, prioritize 7.2 for the quota initialization fixes torvalds/linux [plan]
→ Monitor thermal and cpufreq behavior on Intel systems in early 7.2 testing torvalds/linux [monitor]
