The function btrfs_lookup_inode_extref(` no longer requires transaction handle, insert length, or COW flag, as the only caller now performs a read-only lookup using trans == NULL, ins_len == 0 and cow == 0. This function was introduced in the early days where extref feature was introduced by commitf186373fef("btrfs: extended inode refs"). Then some cleanup was done in commit33b98f2271("btrfs: cleanup: removed unused 'btrfs_get_inode_ref_index'"), which removed the only caller passing trans and other COW specific options.

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.
