Bluetooth: Refactor hci_cs_le_create_conn
This patch does some code refactoring in hci_cs_le_create_conn
function. The hci_conn object is only needed in case of failure,
therefore hdev locking and hci_conn lookup were moved to
if-statement scope.
Also, the conn->state check was removed since we should always
close the connection if it fails.

Bluetooth: /proc/net/ entries for bluetooth protocols
lsof command can tell the type of socket processes are using.
Internal lsof uses inode numbers on socket fs to resolve the type of
sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides
such inode information.
Unfortunately bluetooth related protocols don't provide such inode
information. This patch series introduces /proc/net files for the protocols.
This patch against af_bluetooth.c provides facility to the implementation
of protocols. This patch extends bt_sock_list and introduces two exported
function bt_procfs_init, bt_procfs_cleanup.
The type bt_sock_list is already used in some of implementation of
protocols. bt_procfs_init prepare seq_operations which converts
protocol own bt_sock_list data to protocol own proc entry when the
entry is accessed.
What I, lsof user, need is just inode number of bluetooth
socket. However, people may want more information. The bt_procfs_init
takes a function pointer for customizing the show handler of
seq_operations.
In v4 patch, __acquires and __releases attributes are added to suppress
sparse warning. Suggested by Andrei Emeltchenko.
In v5 patch, linux/proc_fs.h is included to use PDE. Build error is
reported by Fengguang Wu.

powerpc/ftrace: Trace function graph entry before updating index
As Colin Cross ported my x86 change to ARM, he also pointed out that
powerpc is also behind in this fix.
The commit
722b3c746953 "ftrace/graph: Trace function entry before
updating index" fixes an issue with function graph tracing for x86,
where if the called entry function decides not to trace interrupts, it
can fail the check if an interrupt comes in just after the
curr_ret_stack is updated.
The solution is to call the entry function first, then update the
curr_ret_stack if the entry function wants to be traced.

Merge branch 'for-linus' of git://git./linux/kernel/git/mason/linux-btrfs
Pull large btrfs update from Chris Mason:
"This pull request is very large, and the two main features in here
have been under testing/devel for quite a while.
We have subvolume quotas from the strato developers. This enables
full tracking of how many blocks are allocated to each subvolume (and
all snapshots) and you can set limits on a per-subvolume basis. You
can also create quota groups and toss multiple subvolumes into a big
group. It's everything you need to be a web hosting company and give
each user their own subvolume.
The userland side of the quotas is being refreshed, they'll send out
details on where to grab it soon.
Next is the kernel side of btrfs send/receive from Alexander Block.
This leverages the same infrastructure as the quota code to figure out
relationships between blocks and their owners. It can then compute
the difference between two snapshots and sends the diffs in a neutral
format into userland.
The basic model:
create a snapshot
send that snapshot as the initial backup
make changes
create a second snapshot
send the incremental as a backup
delete the first snapshot
(use the second snapshot for the next incremental)
The receive portion is all in userland, and in the 'next' branch of my
btrfs-progs repo.
There's still some work to do in terms of optimizing the send side
from kernel to userland. The really important part is figuring out
how two snapshots are different, and this is where we are
concentrating right now. The initial send of a dataset is a little
slower than tar, but the incremental sends are dramatically faster
than what rsync can do.
On top of all of that, we have a nice queue of fixes, cleanups and
optimizations."
Fix up trivial modify/del conflict in fs/btrfs/ioctl.c
Also fix up semantic conflict in fs/btrfs/send.c: the interface to
dentry_open() changed in commit
765927b2d508 ("switch dentry_open() to
struct path, make it grab references itself"), and since it now grabs
whatever references it needs, we should no longer do the mntget() on the
mnt (and we need to dput() the dentry reference we took).

"This set includes a major redesign of recording the master node for
resources. The old dir hash table, which just held the master node
for each resource, has been removed. The rsb hash table has always
duplicated the master node value from the dir, and is now the single
record of it.
Having two full hash tables of all resources has always been a waste,
especially since one just duplicated a single value from the other.
Local requests will now often require one instead of two lengthy hash
table searches.
The other substantial change is made possible by the dirtbl removal,
and fixes a long standing race between resource removal and lookup by
reworking how removal is done. At the same time it improves the
efficiency of removal by avoiding repeated searches through a hash
bucket.
The other commits include minor fixes and changes."
