The patch titled
alloc_uid: cleanup
has been removed from the -mm tree. Its filename was
alloc_uid-cleanup.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: alloc_uid: cleanup
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Use kmem_cache_zalloc(), remove large amounts of initialisation code and
ifdeffery.
Note: this assumes that memset(*atomic_t, 0) correctly initialises the
atomic_t. This is true for all present archtiectures and if it becomes false
for a future architecture then we'll need to make large changes all over the
place anyway.
