Previously, we guaranteed atomicity of truncate after unclean shutdown with the BCH_INODE_I_SIZE_DIRTY flag - which required a full scan of the inodes btree. Recently the deleted inodes btree was added so that we no longer have to scan for deleted inodes, but truncate was unfinished and that change left it broken. This patch uses the new logged operations btree to fix truncate atomicity; we now log an operation that can be replayed at the start of a truncate.

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.
