[ Upstream commit 4e00422ee62663e31e611d7de4d2c4aa3f8555f2 ] The block size stored in the super block is used by subsystems outside of btrfs and it's a copy of fs_info::sectorsize. Unify that to always use our sectorsize, with the exception of mount where we first need to use fixed values (4K) until we read the super block and can set the sectorsize. Replace all uses, in most cases it's fewer pointer indirections.

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.
