[PATCH] ipc: replace kmalloc and memset in get_undo_list with kzalloc
Simplify get_undo_list() by dropping the unnecessary cast, removing the size variable, and switching to kzalloc() instead of a kmalloc() followed by a memset(). This cleanup was split then modified from Jes Sorenson's Task Notifiers patches.
