Good morning, I'm your host with Linux Kernel Daily for February 4th, 2026.
Three merge commits landed in the mainline kernel today, all focused on critical fixes for the 6.19 release candidate.
Linus Torvalds merged a comprehensive x86 platform driver fix collection from Ilpo Järvinen. This update addresses multiple hardware support issues including quirks for the MECHREVO Wujie 15X Pro laptop, missing NULL pointer checks in classmate-laptop drivers, and fixes for Intel telemetry systems. The merge also…
A second merge from Steve French addressed two memory leaks in the SMB client subsystem. The fixes target the SendReceive function and smb2_open_file function, preventing memory leaks during SMB operations.
The final merge came from David Sterba, fixing a regression in the btrfs filesystem's raid56 implementation. This single-line fix addresses a memory leak in the stripe_uptodate_bitmap allocation that was causing memory to not be properly freed.
What's next: With these fixes targeting RC8, we're approaching the final release of kernel 6.19. Watch for additional last-minute regression fixes as the kernel moves toward general availability.
