linux-next: build failure after merge of the final tree (vfs treerelated)

[Stephen Rothwell]

Hi all,

After merging the final tree, today's linux-next build (sparc32 defconfig)
failed like this:

drivers/tty/sysrq.c: In function 'write_sysrq_trigger':
drivers/tty/sysrq.c:867:3: error: implicit declaration of function 'get_user' [-Werror=implicit-function-declaration]

Caused by commit b1cdabb05024 ("fs: move code out of buffer.c").
Presumably buffer_head.h was implictly including uaccess.h.

I have added the following patch:

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>

Subject: [PATCH] sysreq.c needs uaccess.h for get_user

Commit b1cdabb05024 ("fs: move code out of buffer.c") removed the include
of linux/buffer_head.h which was presumably implictly including uaccess.h
on sparc32.

Fixes this build error:

drivers/tty/sysrq.c: In function 'write_sysrq_trigger':
drivers/tty/sysrq.c:867:3: error: implicit declaration of function 'get_user' [-Werror=implicit-function-declaration]
