Pull vfs fixes from Christian Brauner: - Fix the AT_HANDLE_CONNECTABLE option so filesystems that don't know how to decode a connected non-dir dentry fail the request - Use repr(transparent) to ensure identical layout between the C and Rust implementation of struct file - Add a missing xas_pause() into the dax code employing wait_entry_unlocked_exclusive() - Fix FOP_DONTCACHE which we disabled for v6.15. A folio could get redirtied and/or scheduled for writeback after the initial dropbehind test. Change the test accordingly to handle these cases so we can re-enable FOP_DONTCACHE again * tag 'vfs-6.16-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: exportfs: require ->fh_to_parent() to encode connectable file handles rust: file: improve safety comments rust: file: mark `LocalFile` as `repr(transparent)` fs/dax: Fix "don't skip locked entries when scanning entries" iomap: don't lose folio dropbehind state for overwrites mm/filemap: unify dropbehind flag testing and clearing mm/filemap: unify read/write dropbehind naming Revert "Disable FOP_DONTCACHE for now due to bugs" mm/filemap: use filemap_end_dropbehind() for read invalidation mm/filemap: gate dropbehind invalidate on folio !dirty && !writeback
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.
