The patch titled
ipc: replace kmalloc and memset in get_undo_list with kzalloc
has been removed from the -mm tree. Its filename is
ipc-replace-kmalloc-and-memset-in-get_undo_list-with-kzalloc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
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.
