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.
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.

Default GIDs are marked reserved at the start of the GID table at index 0 and 1 by gid_table_reserve_default(). Currently when default GID is requested, it can still allocates an empty slot which was not marked as RESERVED for default GID, which is incorrect. At least in current code flow of roce_gid_mgmt.c, in theory we can still request to allocate more than one/two default GIDs depending on how upper devices are setup. Therefore, it is better for cache layer to only allow our reserved slots to be used by default GID allocation requests.
