Good morning, it's September 30th, 2026, and this is your Linux Kernel briefing.
Late fixes for version 7.3 are narrow but hardware-critical, with memory flash drivers, real-time clocks, and ARC architecture corrections dominating.
First theme: automated checking is finding real bugs. Both the real-time clock pull, merge 551c722, and the memory technology pull, merge a243ede, describe results from A-I assisted review and fuzzing. For developers, that means less new behavior, more hardening. Examples include a zeroed alarm structure to stop an…
Second theme: flash data integrity. The most important change called out in the M-T-D pull is handling of the Quad Enable bit in S-P-I NAND. The fix avoids updating that bit on devices without one, while enabling it across all dies where it exists, plus corrections for zero available out-of-band area and crashes…
Third: timing and low-level correctness. The clock pull restores alarm support on E-F-I platforms with a runtime capability probe to avoid a regression. Both clock and NAND drivers fix the same ordering bug: initializing interrupt state before requesting the interrupt. On ARC, merge b004c4b corrects an atomic…
What's next: expect…
