GNOME Sushi spacebar preview fix coming to Ubuntu 26.04

The kernel's page cache is charged with maintaining pages (or, more correctly, folios) containing copies of data from files in the filesystem; its performance has a big effect on the performance of the system as a whole. One of the key decisions the kernel must make is when to evict folios from the page cache. At the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Tal Zussman ran a memory-management-track session on how the page cache could be better customized for specific workloads. It will not be much of a spoiler to say that it involves BPF.

[$] Toward better handling of major page faults

A major page fault occurs when a process attempts to access a page that is not currently present in RAM; satisfying such faults usually involves I/O, and can thus take some time. When many threads sharing an address space are generating page faults, the result can be significant lock contention while that I/O takes place. During the memory-management track at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Barry Song led a session to try, yet again, to find an enduring solution to this problem.
