Mainline Linux tree for various devices, only for fun :)
aeb935a455
SHAREABLE flag is set for subvolumes because users can create snapshot for subvolumes, thus sharing tree blocks of them. But data reloc tree is not exposed to user space, as it's only an internal tree for data relocation, thus it doesn't need the full path replacement handling at all. This patch will make data reloc tree a non-shareable tree, and add btrfs_fs_info::data_reloc_root for data reloc tree, so relocation code can grab it from fs_info directly. This would slightly improve tree relocation, as now data reloc tree can go through regular COW routine to get relocated, without bothering the complex tree reloc tree routine.

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.
