The keys being replayed by journal replay have to be synchronized with updates by other threads that overwrite them. We rely on btree node locks for synchronizing - but since btree write buffer updates take no btree locks, that won't work. Instead, simply disable using the btree write buffer until journal replay is finished. This fixes a rare backpointers error in the merge_torture_flakey test.

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.
