-
- As you can see, the resource pointer is also to be freed
- via <function>kfree_nocheck()</function> after
- <function>release_resource()</function> is called. You
- cannot use <function>kfree()</function> here, because on ALSA,
- <function>kfree()</function> may be a wrapper to its own
- allocator with the memory debugging. Since the resource pointer
- is allocated externally outside the ALSA, it must be released
- via the native
- <function>kfree()</function>.
- <function>kfree_nocheck()</function> is used for that; it calls
- the native <function>kfree()</function> without wrapper.
