- uml-replace-one-element-array-with-zero-element-array.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     uml: Replace one-element array with zero-element array
has been removed from the -mm tree.  Its filename was
     uml-replace-one-element-array-with-zero-element-array.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: uml: Replace one-element array with zero-element array
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

To look at users I did:
$ find arch/um/ include/asm-um -name '*.[ch]'|xargs grep -r 'net_kern\.h'
+-l|xargs grep '\<user\>'

Most users just cast user to the appropriate pointer, the remaining ones are
fixed here.  In net_kern.c, I'm almost sure that save trick is not needed
anymore, but I've not verified it.
