Log recovery frees all the inodes stored in the unlinked list, which can cause expansion of the free inode btree. The ifree code skips block reservations if it thinks there's a per-AG space reservation, but we don't set up the reservation until after log recovery, which means that a finobt expansion blows up in xfs_trans_mod_sb when we exceed the transaction's block reservation. To fix this, we set the "no finobt reservation" flag to true when we create the xfs_mount and only set it to false if we confirm that every AG had enough free space to put aside for the finobt.

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.
