[ Upstream commit 7882b0187bbeb647967a7b5998ce4ad26ef68a9a ]
When fast-commit needs to track ranges, it has to handle inodes that have
inlined data in a different way because ext4_fc_write_inode_data(), in the
actual commit path, will attempt to map the required blocks for the range.
However, inodes that have inlined data will have it's data stored in
inode->i_block and, eventually, in the extended attribute space.
Unfortunately, because fast commit doesn't currently support extended
attributes, the solution is to mark this commit as ineligible.

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.
