+for statically allocated IDRs or idr_init() for dynamically
 allocated IDRs.

+You can call idr_alloc() to allocate an unused ID.  Look up
+the pointer you associated with the ID by calling idr_find()
+and free the ID by calling idr_remove().
 
 If you need to change the pointer associated with an ID, you can call
-:c:func:`idr_replace`.  One common reason to do this is to reserve an
+idr_replace().  One common reason to do this is to reserve an
 ID by passing a ``NULL`` pointer to the allocation function; initialise the
 object with the reserved ID and finally insert the initialised object
 into the IDR.
 
 Some users need to allocate IDs larger than ``INT_MAX``.  So far all of
 these users have been content with a ``UINT_MAX`` limit, and they use
-:c:func:`idr_alloc_u32`.  If you need IDs that will not fit in a u32,
+idr_alloc_u32().  If you need IDs that will not fit in a u32,
 we will work with you to address your needs.
 
 If you need to allocate IDs sequentially, you can use
-:c:func:`idr_alloc_cyclic`.  The IDR becomes less efficient when dealing
+idr_alloc_cyclic().  The IDR becomes less efficient when dealing
 with larger IDs, so using this function comes at a slight cost.
 
 To perform an action on all pointers used by the IDR, you can
-either use the callback-based :c:func:`idr_for_each` or the
-iterator-style :c:func:`idr_for_each_entry`.  You may need to use
-:c:func:`idr_for_each_entry_continue` to continue an iteration.  You can
-also use :c:func:`idr_get_next` if the iterator doesn't fit your needs.

+When you have finished using an IDR, you can call idr_destroy()
 to release the memory used by the IDR.  This will not free the objects
 pointed to from the IDR; if you want to do that, use one of the iterators
 to do it.

+You can use idr_is_empty() to find out whether there are any

 If you need to take a lock while allocating a new ID from the IDR,
 you may need to pass a restrictive set of GFP flags, which can lead
 to the IDR being unable to allocate memory.  To work around this,
-you can call :c:func:`idr_preload` before taking the lock, and then
-:c:func:`idr_preload_end` after the allocation.

+idr_preload_end() after the allocation.
