Konstantin Belousov 3407fefef6 Split the vm_page flags PG_WRITEABLE and PG_REFERENCED into atomic ... flags field. Updates to the atomic flags are performed using the atomic ops on the containing word, do not require any vm lock to be held, and are non-blocking. The vm_page_aflag_set(9) and vm_page_aflag_clear(9) functions are provided to modify afalgs. Document the changes to flags field to only require the page lock. Introduce vm_page_reference(9) function to provide a stable KPI and KBI for filesystems like tmpfs and zfs which need to mark a page as referenced.
