Joe Thornber 791188065b dm bufio: add lock_history optimization for cache iterators

Sometimes it is beneficial to repeatedly get and drop locks as part of
an iteration.  Introduce lock_history struct to help avoid redundant
drop and gets of the same lock.

Optimizes cache_iterate, cache_mark_many and cache_evict.

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.
