Commit 1ba98d086f ("Btrfs: detect corruption when non-root leaf has
zero item") introduced comprehensive root owner checker.
However it's pretty expensive tree search to locate the owner root,
especially when it get reused by mandatory read and write time
tree-checker.
This patch will remove that check, and completely rely on owner based
empty leaf check, which is much faster and still works fine for most
case.
And since we skip the old root owner check, now write time tree check
can be merged with btrfs_check_leaf_full().

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.
