[BUG] If there is an extent beyond chunk boundary, currently RST scrub would error out. [CAUSE] In scrub_submit_extent_sector_read(), we completely rely on extent_sector_bitmap, which is populated using extent tree. The extent tree can be corrupted that there is an extent item beyond a chunk. In that case, RST scrub would fail and error out. [FIX] Despite the extent_sector_bitmap usage, also limit the read to chunk boundary.

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.
