commita208b3f132upstream. There's a warning in btrfs_issue_discard() when the range is not aligned to 512 bytes, originally added in4d89d377bb("btrfs: btrfs_issue_discard ensure offset/length are aligned to sector boundaries"). We can't do sub-sector writes anyway so the adjustment is the only thing that we can do and the warning is unnecessary.

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.
