The commit fixes a race condition in the initialization portion of the
driver. The problem was observed while testing with the kernel in the
staging-next tree. The wait on the ready event is signalled prematurely

Staging: batman-adv: Use refcnt to track usage count of batman_if

get_batman_if_by_netdev and get_active_batman_if may leak data from the
rcu protected list of interfaces. The rcu protected list of all gateway
nodes leaks the actual data outside the read-side critical area. This is
not valid as we may free the data using a call_rcu created callback
after we unlock using rcu_read_unlock. A workaround is to provide a
reference count to be sure that the memory isn't freed to early.

It is currently only to implement the already existing functionality and
doesn't provide the full tracking of all usage cases.

Additionally, we must hardif_hold inside the
rcu_read_lock()..rcu_read_unlock() before we attach to the structure
which "leaks" it. When another function now removed it from its usage
context (primary_if, usage on stack, ...) then we must hardif_put it. If
it is decremented to zero then we can issue the call_rcu to the freeing
function. So "put" is not allowed inside an rcu_read_lock.

especially when otherwise extra locking is needed to protect other code
from picking stale elements. It also protects us for emitting to many

This patch remove file system specific (fat_get_block) and vfs calls
from the cyasgadget driver. The current implementation expects user
space to write the file (open, seek to end, 1 byte write), followed by a
call to clear the dirty pages from the the page cache.

Staging: batman-adv: Always synchronize rcu's on module shutdown

During the module shutdown procedure in batman_exit(), a rcu callback is
being scheduled (batman_exit -> hardif_remove_interfaces ->
hardif_remove_interfae -> call_rcu). However, when the kernel unloads
the module, the rcu callback might not have been executed yet, resulting
in a "unable to handle kernel paging request" in __rcu_process_callback
afterwards, causing the kernel to freeze.

The synchronize_net and synchronize_rcu in mesh_free are currently
called before the call_rcu in hardif_remove_interface and have no real
effect on it.

Therefore, we should always flush all rcu callback functions scheduled
during the shutdown procedure using synchronize_net. The call to
synchronize_rcu can be omitted because synchronize_net already calls it.

This is for the Asahi Kasei AK8975 3-axis magnetometer.  It resides within
the magnetometer section of the IIO subsystem, and implements the raw
magn_x,y,z_raw attributes, as well as magn_x,y,z_scale attributes for
converting to Gauss.

Changed to use the magn_x,y,z_scale attributes, and made those attributes
give the scale factor to conert to Gauss.  Also applied more fixes from
feedback.

Keeping mode as an unsigned long.  I'm going to add proper power management
at some point anyway, which would deprecate this attribute.

staging: hv: Convert vmbus driver interface function pointer table to constant

Convert vmbus driver interface function pointer table to constant
The vmbus interface functions are assigned to a constant - vmbus_ops.

Because the vmbus interface function pointer table is converted to a
constant variable -- vmbus_ops, the function GetChannelInterface(),
VmbusGetChannelInterface() and pointer GetChannelInterface are no longer
in use. The deprecated function's work is done by the initialization of
the newly added constant variable vmbus_ops.

I created the new constant variable vmbus_ops and removed the deprecated
function pointer GetChannelInterface in one patch.
