The kernel contains a pair of related filesystems that, among other things,
can be used for shared-memory applications; shmem is an internal mechanism
used within the kernel, while the tmpfs filesystem is mounted and
accessible from user space. As is the case elsewhere in the kernel, these
subsystems would benefit from the addition of large-folio support. During
a joint storage, filesystem, and memory-management session at the 2024 Linux Storage,
Filesystem, Memory-Management and BPF Summit, Daniel Gomez talked about
the work he is doing to add that support.
