On journal read, previously we would do full journal entry validation immediately after reading a journal entry. However, this would lead to errors for journal entries we weren't actually going to use, either because they were too old or too new (newer than the most recent flush). We've observed write tearing on journal entries newer than the newest flush - which makes sense, prior to a flush there's no guarantees about write persistence. This patch defers full journal entry validation until the end of the journal read path, when we know which journal entries we'll want to use.

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.
