Linux Kernel Daily: Late-Cycle Fixes for Crypto and Regmap

Good morning, it's August 11th, 2026, and this is Linux Kernel Daily.
The theme today is late-cycle hardening. Both merges coming through Linus Torvalds' tree are pure fixes, no new functionality, which is exactly what you want to see this close to a release.
First, the crypto tree. Herbert Xu's pull, commit 5eabf07, bundles six separate fixes. A few stand out. There's a lockdep false-positive in rhashtable during rhl-table destruction, the kind of noisy warning that erodes trust in real lockdep splats if left alone. There's a cryptlen calculation bug in Tegra's GCM…
Second theme: regmap's cache correctness. Mark Brown's pull, commit d58772d, addresses something more structural. Regmap's cache core assumed driver-provided default tables were sorted, but that assumption broke in practice, especially when drivers use named register defines instead of raw numbers. The fix moves…
What to remember: if you maintain a crypto driver, double check any cryptlen or scatterlist handling that runs before DMA mapping completes. And if you touch regmap-based drivers, don't rely on your defaults table being pre-sorted anymore, the core now handles it for you.
That's the briefing for August 11th.…
