Error cleanup path in ext4_alloc_branch() calls ext4_forget() on freshly allocated indirect blocks with 'metadata' set to 1. This results in generating revoke records for these blocks. However this is unnecessary as the freed blocks are only allocated in the current transaction and thus they will never be journalled. Make this cleanup path similar to e.g. cleanup in ext4_splice_branch() and use ext4_free_blocks() to handle block forgetting by passing EXT4_FREE_BLOCKS_FORGET and not EXT4_FREE_BLOCKS_METADATA to ext4_free_blocks(). This also allows allocating transaction not to reserve any credits for revoke records.

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.
