The following condition at btrfs_dirty_inode() is redundant:
if (ret && (ret == -ENOSPC || ret == -EDQUOT))
The first check for a non-zero 'ret' value is pointless, we can simplify
this to simply:
if (ret == -ENOSPC || ret == -EDQUOT)
Not only this makes it easier to read, it also slightly reduces the text
size of the btrfs kernel module:
$ size fs/btrfs/btrfs.ko.before
text data bss dec hex filename
1641400 168265 16864 1826529 1bdee1 fs/btrfs/btrfs.ko.before
$ size fs/btrfs/btrfs.ko.after
text data bss dec hex filename
1641224 168181 16864 1826269 1bdddd fs/btrfs/btrfs.ko.after

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.
