$ ls Documentation/mm/w*
ls: cannot access 'Documentation/mm/w*': No such file or directory
$ git grep writeback Documentation/mm
Documentation/mm/multigen_lru.rst:do not require TLB flushes; clean pages do not require writeback.
Documentation/mm/page_migration.rst:2. Ensure that writeback is complete.
Documentation/mm/page_migration.rst:15. Queued up writeback on the new page is triggered.
Documentation/mm/physical_memory.rst:``nr_writeback_throttled``
Documentation/mm/physical_memory.rst: Number of pages written while reclaim is throttled waiting for writeback.
Or are you suggesting I write a new piece of kernel documentation?
If so, I respectfully decline. I've updated the kernel-doc included
