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

Hi Al,

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

In file included from ipc/util.c:28:0:
include/linux/security.h: In function 'security_real_capable':
include/linux/security.h:1885:2: error: implicit declaration of function '__task_cred' [-Werror=implicit-function-declaration]
include/linux/security.h:1885:2: warning: passing argument 2 of 'cap_capable' makes pointer from integer without a cast [enabled by default]

So security.h needs to include linux/cred.h ...

include/linux/security.h: In function 'security_real_capable':
include/linux/security.h:1885:25: error: dereferencing pointer to incomplete type
include/linux/security.h:1885:25: error: dereferencing pointer to incomplete type

include/linux/security.h:1885:25: error: dereferencing pointer to incomplete type
include/linux/security.h:1885:25: error: dereferencing pointer to incomplete type

And linux/cred.h needs to include linux/sched.h :-(

Caused by commit ae1a442f9d95 ("trim security.h").

I have used the vfs tree form next-20111216 again today.
