The discard path is supposed to issue journal flushes when there's too many buckets empty buckets that need a journal commit before they can be written to again, but at some point this code seems to have been lost. Bring it back with a new optimization to make sure we don't issue too many journal flushes: the journal now tracks the sequence number of the most recent flush in progress, which the discard path uses when deciding which buckets need a journal flush.

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.
