Qu Wenruo c9d328c0c4 btrfs: scrub: merge SCRUB_PAGES_PER_RD_BIO and SCRUB_PAGES_PER_WR_BIO
These two values were introduced in commit ff023aac31 ("Btrfs: add code
to scrub to copy read data to another disk") as an optimization.

But the truth is, block layer scheduler can do whatever it wants to
merge/split bios to improve performance.

Doing such "optimization" is not really going to affect much, especially
considering how good current block layer optimizations are doing.
Remove such old and immature optimization from our code.

Since we're here, also change BUG_ON()s using these two macros to use
ASSERT()s.

README

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.
