[$] Revisiting mshare

Description:
Linux can share memory between processes, but each process (almost always)
has its own set of page tables.  In situations where vast numbers of
processes are sharing a memory region, the combined size of the page
tables can exceed that of the shared memory itself.  There has, thus, long
been an interest in enabling unrelated processes to share page tables
referring to shared memory.  Anthony Yznaga is the latest developer to try
to push this idea (known as "mshare") forward; he described the status of
that work in a memory-management-track discussion at the 2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit (LSFMM+BPF).
