Good morning, this is Linux Kernel Daily for May 16th, 2026.
Today's activity focused on critical bug fixes across multiple subsystems, with 19 commits merged and no pull requests.
Linus Torvalds merged Dave Airlie's DRM fixes addressing several critical graphics driver issues. The TTM subsystem received patches preventing infinite loops in swap-out operations and buffer object shrinking. The xe driver saw fixes for use-after-free vulnerabilities and purgeability tracking, while AMD GPU…
The IOMMU subsystem received what maintainer Joerg Roedel called "probably the largest fixes pull-request ever." Intel VT-d fixes include quirks for Q35 graphics devices and bounds checking to prevent null pointer dereferences. AMD-Vi improvements add bounds checking for debugfs operations. Core IOMMU changes…
Filesystem fixes came in for multiple systems. The SMB client received integer overflow protection in read operations and multichannel reconnect improvements. CephFS fixes address folio reference leaks that could trigger OOM conditions, plus buffer management improvements. Btrfs corrected inode size handling after…
The block layer saw NVMe driver improvements including Apple submission queue…
