Over the years we have built up a lot of infrastructure to keep delayed refs in check, mostly by running them at btrfs_end_transaction() time. We have a lot of different maths we do to figure out how much, if we should do it inline or async, etc. This existed because we had no feedback mechanism to force the flushing of delayed refs when they became a problem. However with the enospc flushing infrastructure in place for flushing delayed refs when they put too much pressure on the enospc system we have this problem solved. Rip out all of this code as it is no longer needed. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
