Currently, the kernel protects access to the agent ID allocator on a per port basis using a spinlock, so it is impossible for two apps/threads on the same port to get the same TID, but it is entirely possible for two threads on different ports to end up with the same TID. As this can be confusing (regardless of it being legal according to the IB Spec 1.3, C13-18.1.1, in section 13.4.6.4 - TransactionID usage), and as the rdma-core user space API for /dev/umad devices implies unique TIDs even across ports, make the TID an atomic type so that no two allocations, regardless of port number, will be the same.

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.
