Subject: ipc: replace kmalloc and memset in get_undo_list with kzalloc
From: Matt Helsley <matthltc@xxxxxxxxxx>


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.
