The "fsuid is the inode owner" case is not necessarily always the likely
case, but it's the case that doesn't do anything odd and that we want in
straight-line code. Make gcc not generate random "jump around for the
fun of it" code.
This just helps me read profiles. That thing is one of the hottest
parts of the whole pathname lookup.

By defining the 'stripe_head_state' in 'handle_stripe', we can move
some common code out of handle_stripe[56]() and into handle_stripe.
The means that all accesses for stripe_head_state in handle_stripe[56]
need to be 's->' instead of 's.', but the compiler should inline
those functions and just use a direct stack reference, and future
patches while hoist most of this code up into handle_stripe()
so we will revert to "s.".

'struct stripe_head_state' stores state about the 'current' stripe
that is passed around while handling the stripe.
For RAID6 there is an extension structure: r6_state, which is also
passed around.
There is no value in keeping these separate, so move the fields from
the latter into the former.
This means that all code now needs to treat s->failed_num as an small
array, but this is a small cost.

sh->lock is now mainly used to ensure that two threads aren't running
in the locked part of handle_stripe[56] at the same time.
That can more neatly be achieved with an 'active' flag which we set
while running handle_stripe. If we find the flag is set, we simply
requeue the stripe for later by setting STRIPE_HANDLE.
For safety we take ->device_lock while examining the state of the
stripe and creating a summary in 'stripe_head_state / r6_state'.
This possibly isn't needed but as shared fields like ->toread,
->towrite are checked it is safer for now at least.
We leave the label after the old 'unlock' called "unlock" because it
will disappear in a few patches, so renaming seems pointless.
This leaves the stripe 'locked' for longer as we clear STRIPE_ACTIVE
later, but that is not a problem.

Other places that change or follow dev->towrite and dev->written take
the device_lock as well as the sh->lock.
So it should really be held in these places too.
Also, doing so will allow sh->lock to be discarded.

This is the start of a series of patches to remove sh->lock.
sync_request takes sh->lock before setting STRIPE_SYNCING to ensure
there is no race with testing it in handle_stripe[56].
Instead, use a new flag STRIPE_SYNC_REQUESTED and test it early
in handle_stripe[56] (after getting the same lock) and perform the
same set/clear operations if it was set.

Original commit 2bda8a0c8af... "Disable router anycast
address for /127 prefixes" says:
| No need for matching code in addrconf_leave_anycast() as it
| will silently ignore any attempt to leave an unknown anycast
| address.
After analysis, because 1) we may add two or more prefixes on the
same interface, or 2)user may have manually joined that anycast,
we may hit chances to have anycast address which as if we had
generated one by /127 prefix and we should not leave from subnet-
router anycast address unconditionally.

The docs say the port has to come on in training pattern 1; at this
point, though, ->DP is in normal mode. The intent here is to wait
until the port is in fact sending data, but that doesn't happen since
we've broken the sequence the hardware expects, and the vblank wait will
time out and kvetch in the log.

Consider a 1600x900 panel, upscaling a 1360x768 mode, full-aspect. The
old math would give you:
scaled_width = 1600 * 768; /* 1228800 */
scaled_height = 1360 * 900; /* 1224000 */
if (scaled_width > scaled_height) { /* pillarbox, and true */
width = 1224000 / 768; /* int(1593.75) = 1593 */
x = (1600 - 1593 + 1) / 2; /* 4 */
y = 0;
height = 768;
} /* ... */
This is broken. The total width of scanout would then be 1593 + 4 + 4,
or 1601, which is wider than the panel itself. The hardware very
dutifully implements this, and you end up with a black 45° diagonal from
the top-left corner to the bottom edge of the screen. It's a cool
effect and all, but not what you wanted. Similar things happen for the
letterbox case.
The problem is that you have an integer number of pixels, which means
it's usually impossible to upscale equally on both axes. 1360/768 is
1.7708, 1600/900 is 1.7777. Since we're constrained on the one axis,
the other one wants to come out as an even number of pixels (the panel
is almost certainly even on both axes, and the x/y offsets will be
applied on both sides). In the math above, if 'width' comes out even,
rounding down is correct; if it's odd, you'd rather round up. So just
increment width/height in those cases.
Tested on a Lenovo T500 (Ironlake).

commit fec11dd9a0109fe52fd631e5c510778d6cbff6cc caused
a regression when we have already mounted //server/share/a
and want to mount //server/share/a/b.
The problem is that lookup_one_len calls __lookup_hash
with nd pointer as NULL. Then __lookup_hash calls
do_revalidate in the case when dentry exists and we end
up with NULL pointer deference in cifs_d_revalidate:
if (nd->flags & LOOKUP_RCU)
return -ECHILD;
Fix this by checking nd for NULL.

Hotplug detection is a mode setting operation and must hold the
struct_mutex or risk colliding with other mode setting operations.
In particular, the display port hotplug function attempts to re-train
the link if the monitor is supposed to be running when plugged back
in. If that happens while mode setting is underway, the link will get
scrambled, leaving it in an inconsistent state.
This is a special case -- usually the driver mode setting entry points
are covered by the upper level DRM code, but in this case the function
is invoked as a work function not under the control of DRM.

do_chunk_alloc() also needed an update since it calls btrfs_alloc_chunk()

If the task that initiated the sillyrename ends up being killed by a
fatal signal, then it will eventually return back to userspace and end
up releasing the i_mutex. d_move however needs to be done while holding
the i_mutex.
Instead of using d_move here, just unhash the old and new dentries to
prevent them from being found by lookups. With this change though, the
dentries are now incorrect post-rename and do not reflect the actual
name of the file on the server. I'm proceeding under the assumption
that since they are unhashed that this isn't really a problem.
In order for the sillydelete to still work though, the dname must be
copied earlier when setting up the sillydelete info, and the name must
be recopied if the sillydelete info has to be moved to a new dentry.
