<a href="#summary" aria-hidden="true" class="anchor" id="user-content-summary" style="margin-top: 0; float: left; margin-left: -20px; text-decoration: none; outline: none;"></a>Summary</h2>
<p dir="auto" style="color: #28272d; margin: 0 0 16px;" align="initial">Per the POSIX definition of <a href="https://pubs.opengroup.org/onlinepubs/009695399/basedefs/limits.h.html" rel="nofollow noreferrer noopener" target="_blank" style="margin-top: 0;">limits.h</a>, AIO_LISTIO_MAX and AIO_MAX should not be defined if there is no corresponding limit in the implementation.</p>
<p dir="auto" style="color: #28272d; margin: 0 0 16px;" align="initial">In the RTEMS AIO implementation does not appear to have any inherent design limitations on the number of outstanding requests or number that can be requested. These constants are used arbitrarily to impose unneeded limits.</p>
<p dir="auto" style="color: #28272d; margin: 0 0 16px;" align="initial">The implementation of this Issue will need to address at least the following areas:</p>
<ul dir="auto" style="text-align: initial; list-style-type: disc; margin: 0 0 16px; padding: 0;">
<li style="margin-top: 0; line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Newlib - to remove the constants in limits.h and provide commentary</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">RTEMS - POSIX AIO source and tests to eliminate use of these constants</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">RSB - Update newlib hash</li>
</ul>
<p dir="auto" style="color: #28272d; margin: 0 0 16px;" align="initial">In this case, removing use of the constants in RTEMS before removing them from newlib should avoid the newlib hash bump resulting in breaking builds.</p>
