Red Hat Losing Another Prominent Linux Kernel Engineer

Another highly influential Linux kernel engineer, David Hildenbrand, is leaving Red Hat after a decade of major contributions to memory management, virtualization, and VirtIO. His recent kernel patch updates his maintainer info to a kernel.org address, signaling his departure. He hasn't yet said where he's headed next. Phoronix reports: David Hildenbrand serves as a reviewer for the HugeTLB code, s390 KVM code, and memory management reclaim code. He also serves as an upstream maintainer for the Linux kernel's core memory management code, Get User Pages (GUP) memory management code, kernel samepage merging (KSM), reverse mapping (RMAP), transparent hugepage (THP), memory advice (MADVISE), VirtIO memory driver, and VirtIO balloon driver.

Hildenbrand had been employed by Red Hat the past decade in Munich working on QEMU/KVM virtualization, Linux kernel memory management, VirtIO, and related low-level areas. Just this year alone so far in 2025 he's authored or been mentioned on more than one thousand mainline Linux kernel patches.
