If a transaction is larger than journal->j_max_transaction_buffers, that is a bug and not a trigger for transaction commit. Also the very next attempt to start new handle will start transaction commit anyway. So just remove the pointless check. Arguably, we could start transaction commit whenever the transaction size is *close* to journal->j_max_transaction_buffers. This has a potential to reduce latency of the next jbd2_journal_start() at the cost of somewhat smaller transactions. However for this to have any effect, it would mean that there isn't someone already waiting in jbd2_journal_start() which means metadata load for the fs is pretty light anyway so probably this optimization is not worth it.

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.
