trylock_super(): replacement for grab_super_passive()
I've noticed significant locking contention in memory reclaimer around
sb_lock inside grab_super_passive(). Grab_super_passive() is called from
two places: in icache/dcache shrinkers (function super_cache_scan) and
from writeback (function __writeback_inodes_wb). Both are required for
progress in memory allocator.
Grab_super_passive() acquires sb_lock to increment sb->s_count and check
sb->s_instances. It seems sb->s_umount locked for read is enough here:
super-block deactivation always runs under sb->s_umount locked for write.
Protecting super-block itself isn't a problem: in super_cache_scan() sb
is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
are still active. Inside writeback super-block comes from inode from bdi
writeback list under wb->list_lock.
This patch removes locking sb_lock and checks s_instances under s_umount:
generic_shutdown_super() unlinks it under sb->s_umount locked for write.
New variant is called trylock_super() and since it only locks semaphore,
callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
they're done.

Convert the following where appropriate:

(2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).
(3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more
complicated than it appears as some calls should be converted to
d_can_lookup() instead. The difference is whether the directory in
question is a real dir with a ->lookup op or whether it's a fake dir with
a ->d_automount op.
In some circumstances, we can subsume checks for dentry->d_inode not being
NULL into this, provided we the code isn't in a filesystem that expects
d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
use d_inode() rather than d_backing_inode() to get the inode pointer).
Note that the dentry type field may be set to something other than
DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
manages the fall-through from a negative dentry to a lower layer. In such a
case, the dentry type of the negative union dentry is set to the same as the
type of the lower dentry.
However, if you know d_inode is not NULL at the call site, then you can use
the d_is_xxx() functions even in a filesystem.
There is one further complication: a 0,0 chardev dentry may be labelled
DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was
intended for special directory entry types that don't have attached inodes.
The following perl+coccinelle script was used:
use strict;

Pull one more batch of power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes on top of the previously merged recent PM and
ACPI material.
First, one commit that broke the ACPI LPSS (Low-Power Subsystem)
driver on a Dell box is reverted and there are two stable-candidate
fixes for that driver. Another fix cleans up two recently added ACPI
EC messages that look odd and the printk level of a noisy debug
message in the core ACPI resources handling code is reduced.
In addition to that we have two stable-candidate fixes for the s3c
cpufreq driver, two cpuidle powernv driver updates related to Device
Trees and a PNP subsystem cleanup that will allow us to get rid of
some old ugliness going forward. Also there is a new blacklist entry
for the ACPI backlight code.
Specifics:
- Revert a recent ACPI LPSS driver commit that prevented the touchpad
driver from loading on Dell XPS13 (Jarkko Nikula).
- Make the ACPI LPSS driver disable the I2C controllers and deassert
SPI host controllers resets at startup on Intel BayTrail and
Braswell SoCs in case they have been left in wrong states by the
platform firmware which then may casuse fatal controller driver
failures during resume from hibernation (Mika Westerberg).
- Make two recently added ACPI EC messages look better (Scot Doyle).
- Reduce the printk level of a recently added debug message related
to ACPI resources that may become noisy in some cases (Rafael J
Wysocki).
- Add a new ACPI backlight blacklist entry for Samsung Series 9
(900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native
backlight interface doesn't work while the ACPI based one does
(Jens Reyer).
- Make the PNP sybsystem's core code use __request_region() followed
by __release_region() instead of __check_region() which then will
allow us to get rid of the latter as it has no more users (Jakub
Sitnicki).
- Fix a build breakage and an issue with two __init functions that
may be called after initialization in the s3c cpufreq driver (Arnd
Bergmann).
- Make the powernv cpuidle driver read target_residency values for
idle states from a Device Tree (as we have the suitable DT bindings
for that now) and improve the parsing of the powermgmt DT node in
that driver (Preeti U Murthy)"

"The clock framework changes contain the usual driver additions,

Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
