During log syncing, when we start updating the log root tree we compute
an index value, stored in variable 'index2', once we lock the log root
tree's mutex. This value depends on the log root's log_transid. And
shortly after we compute again the same value for 'index2' - the value
is exactly the same since we haven't released the mutex and therefore
the log_transid of the log root is the same as before.
This second 'index2' computation became pointless after commit
a93e01682e ("btrfs: remove no longer needed use of log_writers for the
log root tree"). So remove it.

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.
