fcloop depends on the host or the target to allocate the fcloop_lsreq object. This means that the lifetime of the fcloop_lsreq is tied to either the host or the target. Consequently, the host or the target must cooperate during shutdown. Unfortunately, this approach does not work well when the target forces a shutdown, as there are dependencies that are difficult to resolve in a clean way. The simplest solution is to decouple the lifetime of the fcloop_lsreq object by managing them directly within fcloop. Since this is not a performance-critical path and only a small number of LS objects are used during setup and cleanup, it does not significantly impact performance to allocate them during normal operation.

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.
