xfs: prepare repair for bulk loading Before we start merging the online repair functions, let's improve the bulk loading code a bit. First, we need to fix a misinteraction between the AIL and the btree bulkloader wherein the delwri at the end of the bulk load fails to queue a buffer for writeback if it happens to be on the AIL list. Second, we introduce a defer ops barrier object so that the process of reaping blocks after a repair cannot queue more than two extents per EFI log item. This increases our exposure to leaking blocks if the system goes down during a reap, but also should prevent transaction overflows, which result in the system going down. Third, we change the bulkloader itself to copy multiple records into a block if possible, and add some debugging knobs so that developers can control the slack factors, just like they can do for xfs_repair.

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.
