Subject: linux-next: build failure after merge of the akpm tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/aio.c: In function 'exit_aio':
fs/aio.c:522:60: error: macro "hlist_for_each_entry_safe" passed 5 arguments, but takes just 4
fs/aio.c:522:2: error: 'hlist_for_each_entry_safe' undeclared (first use in this function)
fs/aio.c:522:2: note: each undeclared identifier is reported only once for each function it appears in
fs/aio.c:522:62: error: expected ';' before '{' token

I added this fix patch:
