Only one of the callers of __add_block_group_free_space() aborts the transaction if the call fails, while the others don't do it and it's either never done up the call chain or much higher in the call chain. So make sure we abort the transaction at __add_block_group_free_space() if it fails, which brings a couple benefits: 1) If some call chain never aborts the transaction, we avoid having some metadata inconsistency because BLOCK_GROUP_FLAG_NEEDS_FREE_SPACE is cleared when we enter __add_block_group_free_space() and therefore __add_block_group_free_space() is never called again to add the block group items to the free space tree, since the function is only called when that flag is set in a block group; 2) If the call chain already aborts the transaction, then we get a better trace that points to the exact step from __add_block_group_free_space() which failed, which is better for analysis. So abort the transaction at __add_block_group_free_space() if any of its steps fails.

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.
