Good morning, this is your Linux Kernel briefing for April 18th, 2026.
Linus Torvalds merged significant pin control updates from Linus Walleij, introducing core improvements for GPIO configuration validation and a new GPIO-by-pin control driver that fulfills Grant Likely's vision of GPIO as a pin control front-end. The merge adds support for multiple new hardware platforms including…
The I3C subsystem received updates from Alexandre Belloni, adding Intel Nova Lake-H support and fixing critical error handling in command processing. Memory leak fixes were implemented across multiple I3C master drivers.
Network driver maintenance included substantial Intel ethernet driver updates addressing race conditions and double-free vulnerabilities. Keita Morisaki fixed a critical race condition in the ice driver's TX timestamp ring cleanup that could cause NULL pointer dereferences. The fix reorders flag clearing operations…
Marek Vasut resolved a deadlock in the ks8851 ethernet driver by reinstating bottom-half disabling around IRQ handlers. The fix prevents softirq scheduling conflicts that could trigger spinlock deadlocks, particularly affecting PREEMPT_RT configurations.
Michael Bommarito…
