commit 193b4e8398 upstream.
We are doing a BUG_ON() if we fail to update an inode after setting (or
clearing) a xattr, but there's really no reason to not instead simply
abort the transaction and return the error to the caller. This should be
a rare error because we have previously reserved enough metadata space to
update the inode and the delayed inode should have already been setup, so
an -ENOSPC or -ENOMEM, which are the possible errors, are very unlikely to
happen.
So replace the BUG_ON()s with a transaction abort.

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.
