[$] Toward better handling of major page faults

A major page fault occurs when a process attempts to access a page that isnot currently present in RAM; satisfying such faults usually involves I/O, and can thus take some time. When many threadssharing an address space are generating page faults, the result can besignificant lock contention while that I/Otakes place. During the memory-management track at the 2026 Linux Storage,Filesystem, Memory Management, and BPF Summit, Barry Song led a sessionto try, yet again, to find an enduring solution to this problem.
