Dunevictable-lru.rst49 * Those mapped into VM_LOCKED [mlock()ed] VMAs.
179 faulted into a VM_LOCKED vma, or found in a vma being VM_LOCKED.
195 There may be situations where a page is mapped into a VM_LOCKED VMA, but the
230 of VM_LOCKED VMAs that map the page. This use of the link field for a count
236 attempting to isolate them, thus abandoning the count of VM_LOCKED VMAs. When
238 replaced by walking the reverse map to determine whether any VM_LOCKED VMAs
245 mlocked pages - pages mapped into a VM_LOCKED VMA - are a class of unevictable
262 and when a VM_LOCKED stack segment is expanded; or
265 reclaim a page in a VM_LOCKED VMA via try_to_unmap()
267 all of which result in the VM_LOCKED flag being set for the VMA if it doesn't
