When the user submits more than 32 work request to a srq queue at a time, it needs to find the corresponding number of entries in the bitmap in the idx queue. However, the original lookup function named ffs only processes 32 bits of the array element, When the number of srq wqe issued exceeds 32, the ffs will only process the lower 32 bits of the elements, it will not be able to get the correct wqe index for srq wqe.

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.
