Once we have inodes pinning the cluster buffer and attached whenever they are dirty, we no longer have a guarantee that the items are flush locked when we lock the cluster buffer. Hence we cannot just walk the buffer log item list and modify the attached inodes. If the inode is not flush locked, we have to ILOCK it first and then flush lock it to do all the prerequisite checks needed to avoid races with other code. This is already handled by xfs_ifree_get_one_inode(), so rework the inode iteration loop and function to update all inodes in cache whether they are attached to the buffer or not. Note: we also remove the copying of the log item lsn to the ili_flush_lsn as xfs_iflush_done() now uses the XFS_ISTALE flag to trigger aborts and so flush lsn matching is not needed in IO completion for processing freed inodes.

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.
