Good morning, it's Saturday, October 17th, 2026, and this is Linux Kernel Daily.
The lead story is a late-cycle shift from features to safety, as core filesystem, graphics, and tracing fixes land ahead of version 7.3.
First, filesystem and core stability. Commit 1dbb742 pulls a set of virtual filesystem fixes focused on use-after-free during R C U path walks. The issue is that anything read in R C U mode must be freed after a grace period, and several filesystems were not doing that — including extended 4 symlinks, N T F S 3…
Second, graphics stabilization. Commit 58161ea merges D R M fixes dominated by A M D G P U, including user pointer leaks, scheduler entity leaks, and a USB 4 null dereference. Maintainers call the most important change a revert of D M A buffer debug tracking, described as technically correct but causing fallout with…
Third, hardware quirks and observability. Commit 4766082 fixes a V F I O passthrough regression on Samsung 990 Pro and 990 Evo Plus N V Me drives that falsely advertise immediate readiness. Commit e2c278b corrects tracing null dereferences for histogram keys and offline C P Us, and commit 9d58691 postpones print…
What's next: test R C U-heavy…
