[HICCUP] Kernels can create file extent items with incorrect ram_bytes like this: item 6 key (257 EXTENT_DATA 0) itemoff 15816 itemsize 53 generation 7 type 1 (regular) extent data disk byte 13631488 nr 32768 extent data offset 0 nr 4096 ram 4096 extent compression 0 (none) Thankfully kernel can handle them properly, as in that case ram_bytes is not utilized at all. [ENHANCEMENT] Since the hiccup is not going to cause any data-loss and is only a minor violation of on-disk format, here we only need to ignore the incorrect ram_bytes value, and use the correct one from btrfs_file_extent_item::disk_num_bytes.

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 reStructuredText 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.
