Hi,
I'm Ryo Onodera. I created this very tiny patch to enable /proc/diskstats for
/dev/ramX.
I'm contacting Nick Piggin as the maintainer of ramdisk ram block.
This is my first patch to the Linux kernel. Sorry if this is not the expected
way of submitting patches.

There are two reasons to remove the "chip" parameter in nand_get_device():
[1] The nand_release_device() does not have the "chip" parameter.
[2] We can get the nand_chip by the mtd->priv field.
This patch removes the "chip" parameter in nand_get_device().

The nand_get_device() does not select the chip, but nand_release_device()
does de-select the chip. It is really strange.
With the current code, nand_sync() will de-select the chip, even if the chip
has never been selected.
To make the balance of select/de-select chip, it's better to remove the

Looks like it is bug in scsi.h with missing definitions in 3.2.34.
I compared scsi.h with one in 3.2.29 kernel and there are lots of

kernel/events/core.c defines a no-op stub of perf_cgroup_switch when
CONFIG_CGROUP_PERF=n. However, nothing actually calls
perf_cgroup_switch outside of an #ifdef CONFIG_CGROUP_PERF. So, drop
the stub.
This also eliminates a warning from gcc (-Wmissing-prototypes) and from

Commit e43473b7f223ec866f7db273697e76c337c390f9 in September 2010
("blkio: Core implementation of throttle policy") re-added the
previously removed function kblockd_schedule_delayed_work, and added a
single call from throtl_schedule_delayed_work in block/blk-throttle.c.

Commit 3ee48b6af49cf534ca2f481ecc484b156a41451d added the
set_iounmap_nonlazy function for use on x86, but actually defined it on
all architectures. Only x86 prototypes this function (in asm/io.h), and
only x86 uses it (in arch/x86/kernel/crash_dump_64.c), so avoid defining
it on non-x86.
