Christoph Hellwig <hch@lst.de> says: While looking at the filemap writeback code, I think adding filemap_fdatawrite_wbc ended up being a mistake, as all but the original btrfs caller should be using better high level interfaces instead. This series removes all these, switches btrfs to a more specific interfaces and also cleans up another too low-level interface. With this the writeback_control that is passed to the writeback code is only initialized in three places, although there are a lot more places in file system code that never reach the common writeback code. * patches from https://patch.msgid.link/20251024080431.324236-1-hch@lst.de: mm: rename filemap_fdatawrite_range_kick to filemap_flush_range mm: remove __filemap_fdatawrite_range mm: remove filemap_fdatawrite_wbc mm: remove __filemap_fdatawrite mm,btrfs: add a filemap_flush_nr helper btrfs: push struct writeback_control into start_delalloc_inodes btrfs: use the local tmp_inode variable in start_delalloc_inodes ocfs2: don't opencode filemap_fdatawrite_range in ocfs2_journal_submit_inode_data_buffers 9p: don't opencode filemap_fdatawrite_range in v9fs_mmap_vm_close mm: don't opencode filemap_fdatawrite_range in filemap_invalidate_inode Link: https://patch.msgid.link/20251024080431.324236-1-hch@lst.de Signed-off-by: Christian Brauner <brauner@kernel.org>
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 reStructuredText 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.
