Jerry Lee 李修賢 67de22cb0b ext4: continue to expand file system when the target size doesn't reach commit `df3cb754d1` upstream. When expanding a file system from (16TiB-2MiB) to 18TiB, the operation exits early which leads to result inconsistency between resize2fs and Ext4 kernel driver. === before === ○ → resize2fs /dev/mapper/thin resize2fs 1.45.5 (07-Jan-2020) Filesystem at /dev/mapper/thin is mounted on /mnt/test; on-line resizing required old_desc_blocks = 2048, new_desc_blocks = 2304 The filesystem on /dev/mapper/thin is now 4831837696 (4k) blocks long.

README

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.
