In the function __rxe_add_to_pool, the function xa_alloc_cyclic is called. The return value of the function xa_alloc_cyclic is as below: " Return: 0 if the allocation succeeded without wrapping. 1 if the allocation succeeded after wrapping, -ENOMEM if memory could not be allocated or -EBUSY if there are no free entries in @limit. " But now the function __rxe_add_to_pool only returns -EINVAL. All the returned error value should be returned to the caller.

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 reStructuredText 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.
