filemap_unaccount_folio() has a WARN_ON_ONCE(folio_test_dirty(folio)). It is good to warn of late dirtying on a persistent filesystem, but late dirtying on tmpfs can only lose data which is expected to be thrown away; and it's a pity if that warning comes ONCE on tmpfs, then hides others which really matter. Make it conditional on mapping_cap_writeback(). Cleanup: then folio_account_cleaned() no longer needs to check that for itself, and so no longer needs to know the mapping.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
