<p>__list_for_each - iterate over a list : the &struct <a class="el" href="../../d9/d93/structlist__head.html">list_head</a> to use as a loop counter. : the head for your list.</p>
|
|
<p>This variant differs from <a class="el" href="../../da/d00/linux__list_8h.html#ab8b24e6660ab3760c923e4b4db3fa502">list_for_each()</a> in that it's the simplest possible list iteration code, no prefetching is done. Use this for code that knows the list to be very short (empty or 1 entry) most of the time. </p>

<p>The caller must take whatever precautions are necessary (such as holding appropriate locks) to avoid racing with another list-mutation primitive, such as <a class="el" href="../../da/d00/linux__list_8h.html#ad16ef5ef2d6e154c3e770176d8a6b5fd">hlist_add_head_rcu()</a> or <a class="el" href="../../da/d00/linux__list_8h.html#a0f031846dfd044009602871bd965561c">hlist_del_rcu()</a>, running on this same list. However, it is perfectly legal to run concurrently with the _rcu list-traversal primitives, such as <a class="el" href="../../da/d00/linux__list_8h.html#a3758c38c0697ac740d62f4d4db56abb4">hlist_for_each_entry()</a>, but only if smp_read_barrier_depends() is used to prevent memory-consistency problems on Alpha CPUs.

<p>list_del_rcu - deletes entry from list without re-initialization : the element to delete from the list.</p>
|
|
<p>Note: list_empty on entry does not return true after this, the entry is in an undefined state. It is useful for RCU based lockfree traversal.</p>
|
|
<p>In particular, it means that we can not poison the forward pointers that may still be used for walking the list.</p>
|
|
<p>The caller must take whatever precautions are necessary (such as holding appropriate locks) to avoid racing with another list-mutation primitive, such as <a class="el" href="../../da/d00/linux__list_8h.html#a3495fef4758575d5f7524d1585043ff0">list_del_rcu()</a> or <a class="el" href="../../da/d00/linux__list_8h.html#a087d5457d659b54dafff3b729c867192">list_add_rcu()</a>, running on this same list. However, it is perfectly legal to run concurrently with the _rcu list-traversal primitives, such as <a class="el" href="../../da/d00/linux__list_8h.html#a8f594017c381faadd03ff91037ef3490">list_for_each_entry_rcu()</a>.</p>
|
|
<p>Note that the caller is not permitted to immediately free the newly deleted entry. Instead, either synchronize_kernel() or call_rcu() must be used to defer freeing until an RCU grace period has elapsed. </p>
