llc: replace the socket list with a local address based hash
For the cases where a lot of interfaces are used in conjunction with a
lot of LLC sockets bound to the same SAP, the iteration of the socket

Replacing the list with a a local address based hash significantly
improves the bind and listener lookup operations as well as the

Connected sockets delivery is also improved, but this patch does not
address the case where we have lots of sockets with the same local
address connected to different remote addresses.
In order to keep the socket sanity checks alive and fast a socket

llc: convert the socket list to RCU locking
For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism,
which require some extra checks in the lookup code:
a) If the current socket was released, reallocated & inserted in
another list it will short circuit the iteration for the current list,
thus we need to restart the lookup.
b) If the current socket was released, reallocated & inserted in the
same list we just need to recheck it matches the look-up criteria and
if not we can skip to the next element.
In this case there is no need to restart the lookup, since sockets are
inserted at the start of the list and the worst that will happen is
that we will iterate throught some of the list elements more then
once.
Note that the /proc and multicast delivery was not yet converted to
RCU, it still uses spinlocks for protection.

The current Linux TCP implementation limits the advertised TCP initial

TCP connections used for transaction type of traffic (i.e. http

in increased latency to complete the transaction.
Support for setting initial congestion window is already supported
using rtnetlink init_cwnd, but the feature is useless without the

USB: emi62: fix crash when trying to load EMI 6|2 firmware
While converting emi62 to use request_firmware(), the driver was also
changed to use the ihex helper functions. However, this broke the loading
of the FPGA firmware because the code tries to access the addr field of
the EOF record which works with a plain array that has an empty last
record but not with the ihex helper functions where the end of the data is
signaled with a NULL record pointer, resulting in:
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<

USB: fix bugs in usb_(de)authorize_device
This patch (as1315) fixes some bugs in the USB core authorization
code:
usb_deauthorize_device() should deallocate the device strings
instead of leaking them, and it should invoke
usb_destroy_configuration() (which does proper reference
counting) instead of freeing the config information directly.
usb_authorize_device() shouldn't change the device strings
until it knows that the authorization will succeed, and it should
autosuspend the device at the end (having autoresumed the
device at the start).
Because the device strings can be changed, the sysfs routines
to display the strings must protect the string pointers by
locking the device.

Staging: comedi: jr3_pci: Don't ioremap too much space. Check result.
For the JR3/PCI cards, the size of the PCIBAR0 region depends on the
number of channels. Don't try and ioremap space for 4 channels if the
card has fewer channels. Also check for ioremap failure.

The flag COMEDI_CB_BLOCK was marked as "depricated in the header file".
However, this flag is important to wake up the data-reader (and writer)

Staging: comedi: usbdux.c: fix locking up of the driver when the comedi ringbuffer runs empty
Jan-Matthias Braun spotted a bug which locks up the driver when the
comedi ring buffer runs empty and provided a patch. The driver would
still send the data to comedi but the reader won't wake up any more.
What's required is setting the flag COMEDI_CB_BLOCK after new data has
arrived which wakes up the reader and therefore the read() command.

Driver-core: Fix bogus 0 error return in device_add()
If device_add() is called with a device which does not have dev->p set
up, then device_private_init() is called. If that succeeds, then the
error variable is set to 0. Now if the dev_name(dev) check further
down fails, then device_add() correctly terminates, but returns 0.
That of course lets the driver progress. If later another driver uses
this half set up device as parent then device_add() of the child
device explodes and renders sysfs completely unusable.
Set the error to -EINVAL if dev_name() check fails.

devtmpfs has a rw_lock dirlock which serializes delete_path and

This code was obviously never tested with the usual set of debugging
facilities enabled. In the dirlock held sections the code calls:
- vfs functions which take mutexes
- kmalloc(, GFP_KERNEL)
In both code pathes the might sleep warning triggers and spams dmesg.
Convert the rw_lock to a mutex. There is no reason why this needs to
