[$] The problem of unnecessary readahead
The final session in the memory-management track of the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit was a brief, last-minute

that may be changing. At the 2025 Linux Storage, Filesystem, Memory
Management, and BPF Summit (LSFMM+BPF), Ted Ts’o led a discussion about
whether the ABI concerns are outweighed by the utility of tracepoints for … ⌘ Read more
