Linux kernel modifications for the Kernel Hacking exam
bedb0f056f
Apply the outstanding statfs changes in the journal head to the master statfs file. Zero out the local statfs file for good measure. Previously, statfs updates would be read in from the local statfs inode and synced to the master statfs inode during recovery. We now use the statfs updates in the journal head to update the master statfs inode instead of reading in from the local statfs inode. To preserve backward compatibility with kernels that can't do this, we still need to keep the local statfs inode up to date by writing changes to it. At some point in the future, we can do away with the local statfs inodes altogether and keep the statfs changes solely in the journal.

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.
