Good morning. This is your Linux Kernel briefing for April 19th, 2026.
Today's activity focused on stability fixes and driver subsystem updates, with 22 commits merged into the mainline kernel.
Linus Torvalds merged critical memory management hotfixes from Andrew Morton, addressing seven issues including use-after-free bugs in block cgroup release and device folio handling. The fixes also resolve problems with DAMON region sizing and weighted memory interleaving. All patches are marked for stable kernel…
Driver core improvements were merged from Danilo Krummrich, implementing a new "ready_to_probe" device flag to prevent race conditions during device initialization. This addresses timing issues that could occur when drivers register concurrently with device setup.
Greg Kroah-Hartman's staging driver updates brought 154 commits of cleanup work, primarily from new kernel developers. The changes include code style improvements and variable type corrections in octeon drivers.
The USB and Thunderbolt subsystem received 176 commits adding new power supply driver support, device tree updates, and enhanced hardware support for StarFive JHB100 and other controllers. Security improvements…
