commit ea8569194b43f0f01f0a84c689388542c7254a1f upstream. When we fail to expand inode from inline format to a normal format, we restore inode to contain the original inline formatting but we forgot to set i_lenAlloc back. The mismatch between i_lenAlloc and i_size was then causing further problems such as warnings and lost data down the line.

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.
