Next patch converts ext2 to use iomap interface for DIO. iomap layer can call generic_write_sync() -> ext2_fsync() from iomap_dio_complete while still holding the inode_lock(). Now writeback from other paths doesn't need inode_lock(). It seems there is also no need of an inode_lock() for sync_mapping_buffers(). It uses it's own mapping->private_lock for it's buffer list handling. Hence this patch is in preparation to move ext2 to iomap. This uses generic_buffers_fsync() which does not take any inode_lock() in ext2_fsync().

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.
