https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-12137 Lustre <p>Since kernel commit <tt>v4.6&#45;rc3&#45;29&#45;g6192269</tt> there is a new <tt>&#45;&gt;iterate&#95;shared()</tt> file operation for reading directories with a shared lock on the client. We should change over the llite client to use the <tt>&#45;&gt;iterate&#95;shared()</tt> method to improve directory access concurrency on the client. </p> <p>There is already a <tt>HAVE&#95;ITERATE&#95;SHARED</tt> configure check that can be used to detect support for this functionality. </p> LU-12137
