The driver's queuecommand routine is still wrapped to hold the host lock for the duration of the call. This will become problematic when moving to multiple queues due to the lock contention preventing asynchronous submissions to mulitple queues. There is no real legitimate reason to hold the host lock, and previous patches have insured proper protection of moving ibmvfc_event objects between free and sent lists.

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.
