If we crash when the journal pin fifo is completely full - i.e. we're at the maximum number of dirty journal entries - that may put us in a sticky situation in recovery, as journal replay will need to be able to open new journal entries in order to get going. bch2_fs_journal_start() already had provisions for resizing the journal pin fifo if needed, but it needs a fudge factor to ensure there's room for journal replay.

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.
