mainlining shenanigans

perag reservation is enabled at mount time on a per AG basis. The upcoming change to set aside allocbt blocks from block reservation requires a populated allocbt counter as soon as possible after mount to be fully effective against large perag reservations. Therefore as a preparation step, initialize the pagf on all mounts where at least one reservation is active. Note that this already occurs to some degree on most default format filesystems as reservation requirement calculations already depend on the AGF or AGI, depending on the reservation type.

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.
