Linus Torvalds bf3aa9de7b New code for 6.11:
* Enable FITRIM on the realtime device.
   * Introduce byte-based grant head log reservation tracking instead of
     physical log location tracking.
     This allows grant head to track a full 64 bit bytes space and hence
     overcome the limit of 4GB indexing that has been present until now.
   * Fixes
     - xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT extents
       in the flush unmap range.
     - Implement bounds check when traversing log operations during log replay.
     - Prevent out of bounds access when traversing a directory data block.
     - Prevent incorrect ENOSPC when concurrently performing file creation and
       file writes.
     - Fix rtalloc rotoring when delalloc is in use
   * Cleanups
     - Clean up I/O path inode locking helpers and the page fault handler.
     - xfs: hoist inode operations to libxfs in anticipation of the metadata
       inode directory feature, which maintains a directory tree of metadata
       inodes. This will be necessary for further enhancements to the realtime
       feature, subvolume support.
     - Clean up some warts in the extent freeing log intent code.
     - Clean up the refcount and rmap intent code before adding support for
       realtime devices.
     - Provide the correct email address for sysfs ABI documentation.

  Fixes:

   - xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT
     extents in the flush unmap range

   - Implement bounds check when traversing log operations during log
     replay

   - Prevent out of bounds access when traversing a directory data block

   - Prevent incorrect ENOSPC when concurrently performing file creation
     and file writes

   - Fix rtalloc rotoring when delalloc is in use

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.
