Goldwyn Rodrigues a8eec69797 btrfs: mark compressed range uptodate only if all bio succeed
commit 240246f6b913b0c23733cfd2def1d283f8cc9bbe upstream.

In compression write endio sequence, the range which the compressed_bio
writes is marked as uptodate if the last bio of the compressed (sub)bios
is completed successfully. There could be previous bio which may
have failed which is recorded in cb->errors.

Set the writeback range as uptodate only if cb->errors is zero, as opposed
to checking only the last bio's status.

Backporting notes: in all versions up to 4.4 the last argument is always
replaced by "!cb->errors".

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.
