There are already two bugs (one in zlib, one in zstd) that involved compression path is not handling sector size < page size cases well. So it makes more sense to make sure that btrfs_compress_folios() returns Since we already have two bugs (one in zlib, one in zstd) in the compression path resulting the @total_in be to larger than the to-be-compressed range length, there is enough reason to add an ASSERT() to make sure the total read-in length doesn't exceed the input length.

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 reStructuredText 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.
