<div dir="ltr"><div>Hi Rohan,</div><div><br></div>I am using 3.10.0-123.el7.x86_64 kernel (RHEL-7). I am trying to obtain 'dentry' value from file path information. For this: earlier I had written the code as below :<div><br></div><div>
<p class="">#if(LINUX_VERSION_CODE >= KERNEL_VERSION(<span class="">2</span>,<span class="">6</span>,<span class="">39</span>))</p><p class=""><span class=""> </span><span class=""> </span>err= kern_path_parent(tmp,nd);</p><p class="">#else</p><p class=""><span class=""> </span><span class=""> </span>err= path_lookup(tmp, <span class="">0</span>, nd);</p><p class="">
</p><p class="">#endif</p><div><div>Now that "nameidata" structure is not exposed with kernel version >= 3.6.0</div></div></div><div>I used kern_path_create() which is returning invalid dentry value.</div><div>
<p class=""><span class=""> </span><span class=""> </span>dentry =kern_path_create(AT_FDCWD, tmp, path, <span class="">1</span>);</p><p class="">So, I tried using : user_path_at() , kern_path() which are not helping me.</p>
<p class="">How to fetch 'dentry' data from file name ? </p></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 7, 2015 at 12:45 PM, Rohan Puri <span dir="ltr"><<a href="mailto:rohan.puri15@gmail.com" target="_blank">rohan.puri15@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Mon, Sep 7, 2015 at 12:10 PM, Pria Mn <span dir="ltr"><<a href="mailto:pria.mn9@gmail.com" target="_blank">pria.mn9@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div>
