The RMC cache has 256 list heads plus a u32, which puts it at the
unfortunate size of 4104 bytes with padding. kmalloc() will then
round this up to the next power-of-two, so we wind up actually
using two pages here where most of the second is wasted.

The mesh_path_reclaim() function, called from an rcu callback, cancels
the mesh_path_timer associated with a mesh path. Unfortunately, this
call can happen much later, perhaps after the hash table itself is
destroyed.
Such a situation led to the following crash in mesh_path_send_to_gates()
when d

Hi Luca,

In the unlikely case that mesh_rmc_init() fails with -ENOMEM,
the rmc pointer will be left as NULL but the interface is still

If this happens, we would blindly dereference rmc when checking

Since we have converted the mesh path tables to rhashtable, we are
no longer swapping out the entire mesh_pathtbl pointer with RCU.
As a result, we no longer need indirection to the hlist head for
the gates list and can simply embed it, saving a pair of
pointer-sized allocations.

The memory allocated by kzalloc in b43_bus_dev_ssb_init and
b43_bus_dev_bcma_init is not freed.
This patch fixes the bug by adding kfree in b43_ssb_remove,
b43_bcma_remove and error handling code of b43_bcma_probe.

With current driver, it is observed that a URB is not
completed while the USB disconnect is initiated. Due to
that, the URB completion hanlder is trying to access
the resource which was freed as a part of USB disconnect.
