- title: 'FetchBPF: Customizable Prefetching Policies in Linux with eBPF'
  authors:
  - Xuechun Cao
  - Shaurya Patel
  - Soo-Yee Lim
  - Xueyuan Han
  - Thomas Pasquier
  reason: Extends eBPF into the page-fault / prefetch path, giving user-space programs
    a safe, low-overhead hook to install custom hardware-prefetch policies without
    kernel modifications.
- title: Fast (Trapless) Kernel Probes Everywhere
  authors:
  - Jinghao Jia
  - Michael V. Le
  - Salman Ahmed 0001
  - Dan Williams 0001
  - Hani Jamjoom
  - Tianyin Xu
  reason: Eliminates the trap-based overhead of kprobes by using binary rewriting
    to instrument kernel functions at near-zero cost, enabling always-on production
    tracing.
- title: 'FBMM: Making Memory Management Extensible With Filesystems'
  authors:
  - Bijan Tabatabai
  - James Christopher Sorenson III
  - Michael M. Swift
  reason: Proposes delegating Linux virtual-memory management to filesystem drivers
    via a clean abstraction layer, opening the OS memory subsystem to the same extensibility
    that filesystems enjoy.
- title: Limitations and Opportunities of Modern Hardware Isolation Mechanisms
  authors:
  - Xiangdong Chen
  - Zhaofeng Li 0004
  - Tirth Jain
  - Vikram Narayanan
  - Anton Burtsev
  reason: Empirically evaluates Intel MPK, RISC-V sPMP, and related primitives and
    shows that their performance and safety properties diverge sharply from vendor
    claims, motivating a fresh look at hardware-assisted compartmentalization.
- title: 'FastCommit: resource-efficient, performant and cost-effective file system
    journaling'
  authors:
  - Harshad Shirwadkar
  - Saurabh Kadekodi
  - Theodore Y. Ts'o
  reason: Redesigns ext4 journal commits to write only changed metadata deltas rather
    than full blocks, slashing journaling overhead while preserving crash consistency
    — and is already deployed in the Linux kernel.
- title: 'ZMS: Zone Abstraction for Mobile Flash Storage'
  authors:
  - Joo Young Hwang
  - Seokhwan Kim
  - Daejun Park 0002
  - Yong-Gil Song
  - Junyoung Han
  - Seunghyun Choi
  - Sangyeun Cho
  - Youjip Won
  reason: Introduces a zone-based abstraction that exposes the append-only write semantics
    of mobile UFS flash to the OS, cutting write amplification and GC overhead by
    an order of magnitude on mobile workloads.
- title: 'Ethane: An Asymmetric File System for Disaggregated Persistent Memory'
  authors:
  - Miao Cai 0001
  - Junru Shen
  - Baoliu Ye
  reason: Proposes a split-path file system design where reads bypass the server entirely
    and writes use lightweight logging, achieving near-DRAM read latency on disaggregated
    persistent memory.
- title: 'StreamCache: Revisiting Page Cache for File Scanning on Fast Storage Devices'
  authors:
  - Zhiyue Li
  - Guangyan Zhang
  reason: Demonstrates that the Linux page cache becomes a bottleneck — not a benefit
    — for sequential scans on NVMe SSDs, and replaces it with a lightweight streaming
    buffer that halves latency for analytical workloads.
- title: 'PeRF: Preemption-enabled RDMA Framework'
  authors:
  - Sugi Lee
  - Mingyu Choi
  - Ikjun Yeom
  - Younghoon Kim
  reason: Adds fine-grained preemption to RDMA by intercepting work-queue operations
    at the NIC driver level, enabling priority isolation for latency-sensitive RPC
    traffic sharing a fabric with bulk transfers.
- title: 'OSMOSIS: Enabling Multi-Tenancy in Datacenter SmartNICs'
  authors:
  - Mikhail Khalilov
  - Marcin Chrapek
  - Siyuan Shen
  - Alessandro Vezzu
  - Thomas Benz
  - Salvatore Di Girolamo
  - Timo Schneider
  - Daniele De Sensi
  - Luca Benini
  - Torsten Hoefler
  reason: Designs an OS-like resource manager for SmartNIC compute and memory that
    enforces tenant isolation and QoS, showing that shared-SmartNIC deployments are
    practical without sacrificing performance.
- title: 'mmTLS: Scaling the Performance of Encrypted Network Traffic Inspection'
  authors:
  - Junghan Yoon
  - Seunghyun Do
  - Duckwoo Kim
  - Taejoong Chung
  - KyoungSoo Park
  reason: Splits TLS session state across multiple cores using a novel sharding scheme,
    removing the per-connection serialization bottleneck in middlebox TLS inspection
    and achieving near-linear multi-core scaling.
- title: 'UniMem: Redesigning Disaggregated Memory within A Unified Local-Remote Memory
    Hierarchy'
  authors:
  - Yijie Zhong
  - Minqiang Zhou
  - Zhirong Shen
  - Jiwu Shu
  reason: Collapses the local/remote memory distinction into a single unified hierarchy
    with a new page-placement runtime, achieving transparent memory disaggregation
    with significantly lower tail latency than prior CXL-based approaches.
