Linux kernel source tree
129854f061
In a follow-on patch, we will reuse long term buffers when possible. When doing so we have to be careful to properly assign map ids. We can no longer assign them sequentially because a lower map id may be available and we could wrap at 255 and collide with an in-use map id. Instead, use a bitmap to track active map ids and to find a free map id. Don't need to take locks here since the map_id only changes during reset and at that time only the reset worker thread should be using the adapter. Noticed this when analyzing an error Dany Madden ran into with the patch set.

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.
