Description:
For every page of memory in the system, the kernel maintains a set of page flags describing how the page is used and various aspects of its current
state. Space for page flags has been in chronic short supply , leading to a desire to
eliminate or consolidate them whenever possible. That objective, though,
is hampered by the fact that the purpose of many page flags is not well understood. In a memory-management-track session at the 2024 Linux Storage, Filesystem, Memory-Management and BPF Summit , Matthew Wilcox set out to cooperatively update the page-flag documentation to improve that situation.
