lov - the logical object volume manager - is responsible for
striping data across multiple volumes.
So when it is given a request, it creates one or more
sub-requests, one for each target volume. Each sub_io
request has a sub_env environment which it operates in.
When lov_io_data_version_end() calls lov_io_end_wrapper() to
wait for and close off a sub_io, it passes the wrong
environment.
This causes an LINVRNT() to fail in cl2osc_io(), and may
cause other problems.
This patch changes the call to use ->sub_env, much like
other code in the same file.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
