[$] Fleshing out memory descriptors

Date:
Mon, 27 May 2024 13:39:04 +0000

Description:
One of the long-term goals of the folio conversion in the kernel's
memory-management subsystem is the replacement of the page structure, which 
describes a page of physical memory, with an eight-byte
"memory descriptor".  This change would reduce the overhead of tracking
physical memory, increase type safety, and make memory management more
flexible.  Thus far, though, details on what the memory-descriptor future
will look like have been relatively scarce.  At the 2024 Linux Storage,
Filesystem, Memory-Management and BPF Summit , Matthew Wilcox led a
discussion to try to fill in the picture somewhat.
